 Hey, good evening guys, can you all hear me? Good evening, good evening to everyone. So we will wait for others to join in. Meanwhile, you can log in into. The mentee site that is mentee.com and use the code 545785, which there on your screen. Now I would request you to log in on a PC maybe, and whenever you know, because there could be some issues related to the resolution. So hence, try to, you know, first. Logging into a PC so that you can zoom in, zoom out. OK, so you can start. Yeah, so all of you are able to join because I can. I don't see anyone here. All of you have done it. John joined this mentee.com code 544. So just give me a second. So now 39 people have joined in. We will wait. Right now we haven't started. First of all, first learning to all of you is stay calm. Stay calm. I have seen, you know, this is, I think, third on this mentee platform, I think, or second. So you guys, you know, I don't know, chemistry was first in physics, then this is, I think, right? Or this is the second mentee test, third for you, right? So in stay calm, first learning is don't panic. If you panic, most of the things go wrong. Yes, there will be further. You know, we will be checking fastest single first for some time. Don't worry about your positions here and there. First 5, 10 and all that. Right now we are all calibrating. We will see how we can, you know, add various elements to it, but you guys have to coordinate and contribute in this exercise for your learning only. Yes, please do not, you know, I see a lot of, you know, this is not working. My option D is not there. The question is wrong. This is real life thing. It will happen multiple number of times. Be ready. We are also trying to minimize that, but it is, it is for some time it will happen. So hence, no need to, yeah, okay. So someone has to just put the mic on mute all the time. So I'm saying. Password for the, password is there on the screen here. See the, see the password, so mentee.com 545785 every time it will be there. Right? The link will be there on the screen and the code will be there on the screen. Okay. So what I was saying is last time. I can't see the screen thing, can't see the screen. Okay. I will start at the screen share. No problem here. No problem, no problem. Yep. So just see the screen now. Okay. All well. All cool. Correct. So hence, first thing, you know, the focus should be on the learning part of it because the questions would be in such a way that they will not be regular, right? So hence, it's not about only winning the quiz today. Even if you win big deal, you know, the, no one is going to, you know, pay any heat to it. In fact, in terms of, let's say, you know, what happens after let's say two, three months down the line. So this is just to keep you, you know, you know, keep you attracted towards squeezing and all. So as I told you, I am developing the other quizzes as well. So we will be mostly doing other subject quizzes, which will be fact based as well. Okay. So yeah. So those who are still struggling, 56 people have joined for those who have just joined in. Go to menti.com. This, the link is there on the screen and the code is also there on the screen. You have to put your screen name. So don't really put any random name because that thing, if let's say, you know, the top 10, we are going to publish their names as well. Sooner, not now. We will be, you know, so all of you must, you know, do some practice over here. Once we are familiar with the entire ecosystem of this mentee and the quizzing, then we'll add other elements as well. For that, you need to be, you know, cooperating with us. So don't really, you know, you guys start panicking and then, you know, we think that our purpose is getting defeated. So hence, stay calm. It might so happen that you lose this quiz. World is not going to be over in one quiz. So hence, stay calm, you know, so don't really... So focus should be what is the question, whether I was able to answer that question. So this will be the protocol. The protocol would be, we will be playing a question. The question you have to solve. Now we have also the data which says that most of you are randomly guessing. So next time onwards, as a disincentive to you, those who will be, you know, because the data says that lots of people are randomly guessing the answer and by fluke or something, they are getting it correct. But those people who are guessing the answer and they are not getting it correct, unfortunately they will have to be barred from the quiz. So they will just view, they will not participate. So beware if you are guessing the answer and it is consistently getting wrong. Then the person who was doing guesswork will be barred from taking the quiz. He can only view, he cannot participate. So please, please take care of that. So hence, we want you to spend time on the question whether the net is lagging or whatever. Yes, so hence the person, he will not be checked out. He will be just, he will be a viewer only. He will not be participating in quizzing. So hence, yes. So the idea is not to see who has the fastest finger here. The idea is to see who has the fastest calculation and thinking power, okay? So hence, it's for all of you. The rule applies to all of you. In the next three days, we will analyze all the data of who is, you know, just guessing it because if you're guessing it, you're getting it correct. No problem. Then you're really genius. But if you're guessing it, then it is going to be wrong. Consistently, let's say the next five, six questions consistently, you're getting it wrong and your timing is very short, small. Then my dear friend, stay, you know, ready, be prepared for only being a viewer of this quiz. Okay? So hence, all of you have to think through the problem. Now, yes, please concentrate here for some time. No, put your mics on mute all the time. Now what I'm trying to tell you is, listen. Yeah, what? Okay, so yes, please pay attention. No chatting over there. Now, all of you pay attention to what I'm just saying. I'm saying is that you look at the question, think on it, solve and then mark your answer because all that data is being captured, my dear friends. So obviously those who will be doing it properly will be rewarded properly as well, okay? So now we are going to start. Anyone else wants to join or change your computer or yep, anything about it? Joining quick, joining quick, okay? So all of you must join before we start because once we start, you will not be able to join. The link is there on the screen and the code is there on the screen. Next time another announcement, next centaur onwards, we will start sharp at 8.02, maximum 8.03. 8.02, 8.03, that is eight, two minutes past or three minutes past after that. We'll start the quiz. Okay, all set. Can we start? Okay. Okay, so here comes the first question of the evening. Again, think and then, and yes, whatever is your observation on the question, if it is a technical glitch, you have to just accept it, move forward. Here we start. So here's the first question of the evening. Which of the following is a mixed repeating decimal form? Take your time, no need to hurry. No need to rush through the answers, okay? You will be getting 100 seconds to mark it. So just, just take your time and whether there is an option missing or something, we will take care of that. Don't worry, just solve the problem. And yes, put your mic on mute here, mute. No problem. No, Munisha, the idea is not to make you slow, dear. Please understand. The idea is that no need to, you know, change your behavior if you're, that's what I said. If you're consistently performing, no worries. But then I have some data where people are just marking it. So I want you to all, you know, mark it, mark it. You know, right now it is for accuracy. The thing which we'll be targeting today or onwards or let's say a couple of months down is accuracy. All of you should get 10 on 10. Whether you take two hours, I don't mind. Okay, no problem, good. So patience always pays. And there are still some people who haven't voted or mark the answer. I would request all of you to mark the answer and then we can proceed, okay? Okay, so who else is there who's still? Am I the only person or I myself have not done it? Maybe wait a minute, but I'm not playing. Oh, I'm playing. Okay, so I'll have to just close this because I should not play. It will be conflict of interest. I know all the answers actually. Okay, so I am out on the race. Okay, fair enough. So last six, five, four, three, two, one. Answer, you can write on the, this thing. So what is, oh my God, still some people have, you know, confusion in this. One more, too easy. One more to 16, I never mind now. So those people clearly, they have few confusion so I have to explain that. So this is the question, this is also the question. Correct, now what is mixed repeating decimal form? You know that there are two types of decimal form for any rational number. This is what we discussed. Any rational number can be expressed in two forms. Pure or rational number can be terminating decimal or a non-terminating but repeating. Correct, non-terminating but repeating. In non-terminating but repeating as well, there are two varieties. One is called pure form and the other is called mixed form. So what are the varieties? Pure form, I told you this typical, all the digits are repeated after decimal are pure form. But only few are, you know, not all are repeated. For example, this one, which was option C here if you see. So digit one and two are not repeating. So hence, this is mixed form. Okay, no problem. Okay, clear, any doubt or any question on this? Please put an X, okay? If you have any doubt on this, this is just a fact-based question, no brainer in it. Sir, this is the fastest person. I'm sorry? Who answered the fastest? That we'll see later. No worries, we'll see, we are going to see that. Wait, okay. Here is the, now. Sir, I have a question. Yes, please go ahead. Sir, in the option D, which was 3.77 bar zero zero, how will that be expressed? Like if you want to express it. So that, it's actually a wrong option only. That's what, so hence, you know, I have purposefully deliberately got into that. You know, this is, it has got no significance. So because seven will keep repeating, so when will the zero zero come right? Obviously, hence, it is not possible. It is a wrong, you know, wrong entity itself. This is a wrong entity itself, right? So this is anyways, so someone who can, who saw this first would have eliminated anyways, right? Yes, I'm correct. Here is the leaderboard. Is that understood? Is this question answered to everyone? Right? So here is the first leaderboard, first leaderboard of the evening. Very good, Rishabh from Nafal. You know, he is leading. Oh my God. Within no time, he has clicked it. I hope he consistently does it. So that consistency, guys, now you have to see consistency, right? So if there is a lot of change in the leaderboard, that means consistency is not there. Okay, next question. Are you ready for the next? Next question. Here is the next question. Why is it that you're not ready? Come on, start. So if you want, you can zoom in a little bit. Okay, so that will help you to read this. If X is 9.17 bar, what is 100X minus X? Take your time, yes, good. Take your time and then answer. Take your time and then answer. So if X is 9.17 bar, I hope you understand this 9.17 bar we have discussed. So 9.17171717 and 100X minus X will be equal. Okay, come on. So we have 100 seconds and most of you have already voted. So, yep. Mention your answer, guys. Mention, mention, mention your answers. Come on, come on, I hope. So if you're not able to see it properly, I would 100 seconds I have given Raghav so that everyone can answer. No problem, no problem. If there are, right, no problem. Take your time, Krish. See, right now there is no problem in taking time. Even if, you know, but make sure that you are correct every time. That's very critical. So that's very critical, okay? Yeah. So right now, all of you should be focusing on accuracy than more on speed. Speed automatically comes with accuracy. I'm telling you from my experience, right now, just focus on speed. And forget, sorry, focus on accuracy. And whatever is happening in the world, forget about that. Just focus on the question right now, okay? Okay. Okay. Now three, two, one. So what is the answer? Let's see the answer. Okay. So D is the most favorite answer. Many people have, you know, gone wrong. I hope this is understood to all. This is how it has to be done. So if X is 9.17 bar, you know what to do. Yes. The answer X, dear friend, will be 917.7 bar. That is what we catch up the question. And X is anyways 9.17 bar. So if you subtract it, you will get 99 X. Oh, sorry, whatever it is, 100 X minus X is 99 X, which is not important. The result is 908, right? Anyone wants an explanation of this? Very easy. Easy or not? Easy or not? Right? Easy or not? Very good. So, right? Okay, next. Don't worry about being last or being first, guys. Again, again, again, I'm trying to tell you be consistent right now. Okay. Here is the leaderboard. And the answer is on the top most position. Okay. Very good. Very good. Oh, no, the eyes, you know, fastest hand on. Clear. Now we can move ahead, guys. Ready? Ready for the next question. Here comes the next question. So here again, similar type of question. Let me see who answers it. This is where you can actually apply your elimination skills also. So this question is very, very straightforward and very easy to mark. Take your time. Take your time. Relax. The idea is to get it right. Not the fastest as of now. Get it right. Even if you are at the last position of the leaderboard, doesn't matter. But be sure that you are 100% accurate. 100% accurate. So Rudra Ditya. So, hence, by mistake, it happens when you are rushed to mark up answer. Right? So all of you see, I have the data at the back end. So those who people who will be 100% accurate rest assured I'm going to treat you whenever the lockdown, you know, is over. I am taking all of you out for a good lunch, maybe somewhere or destination of your choice. Okay. So destination of your choice, lunch, all of you, those who are 100% or 90% above consistency wise, not always. Taco Bell, ice cream, JKF, DKF, GS, whatever. We will go. Okay. Your choice. Okay. Okay. One. Now the time is going to be over. Time is going to be over. Down is going to be over. Time is going to be over. Over. 10. Why do lockdown isn't ending? Raghav, don't worry. Life is going to come back to normalcy. Here is where it ends, right? So the answer, okay? Here is most of you have marked A, but still people are struggling in, you know, finding the right answer. So the explanation to this is something like this. So clearly if X is this much, 1000X, those who have observed this and those who have done the observation activity which I had given you, clearly this is not going to be a integer. Yes, no parallel talks. You come over some other day, we'll have lots of parallel talks. I also love doing that. Don't worry. So 1000X is 10, 0, 1, 7, 0.7 bar. Okay. This is 1000X. No, no. 10 times X will be simply 1, 0, 0.17 bar. Now clearly the decimal part is not same. So hence if you, yeah, once again, Jhagrav is asking how, so if you multiply this by 1000, so 0, 1, 7, and it will come after 7, isn't it? 1000 times. Jhagrav, is this correct? 1000X is this. And 10X will be simply 1 decimal point shift. So 100.17 bar. No, not on both, only on 7. Thanks. I think that is what you are trying to point out this one. Correct? So hence what will happen? If you subtract, obviously it is after decimal, if you see, this is 7, 7, 7, 7 and all that. And here it is 0.17, 7, 7 and all that. Clearly this is not an integer. So all of them are ruled out. Okay. So most of you have, you know, 34. That is exactly 50% people have marked it correct. But those who could not please understand where did you go wrong? And here is the leaderboard. After the third question, guys. Right? So here is the new leaderboard. So Karun followed by Raga followed by Ashish. No, it's going to change. No. Oh, Raga was fastest here. Very good. So you observed it. Okay. Now, no worries. Who's over is where? No, it doesn't matter. Let's go and make sure that the next question is 100% correct. Okay. Shall we go? Move to the next question. Mute your mic always, please. Right? This is the next question. Be ready. Okay. So convert 0.123 bar into P by Q form. This is very, very simple. And you have to reduce it to the simplest form again, giving you that, you know, reduce it to simplest form. I'm giving you hint. Simplest form. Just don't mark it blindly. A piece of pen and a piece of paper and a pen and solve it in front of you right now. Don't try to solve it in your mind. Take a piece of paper and then write on it and then solve. Good. I really appreciate you all, you know, keeping my words and you know, you're adhering to what I have suggested. So most of you are taking time and solving. You will do good. Trust me. Focus on accuracy. 100%. You should not go wrong. That's it. 100 seconds are more than enough. You should not go wrong. I repeat, you should not go wrong. Whatever it takes. Right? Yes. Good. Take your time, guys. Take your time. Take your time. Still 24 seconds left. Still 24 seconds left. Take your time and mark it so that it's correct. Mark it so that it's correct. Mark it so that it's correct. Correctness. Being 100% accurate is what we are looking for. Okay. So here is the time's up. So the correct answer. Oh my God. So we have a variety of people choosing. I told you we have to reduce it to the simplest form. So most of you haven't. I believe. Reduce it to simplest form and hence 22 people have marked it. Right? Wrongly. So here is the explanation to it. So very easy. You have all done it in our classes and you know, you have practiced also. So X is 0.1, 2, 3 bar. Right? Very good. Very good. Keep it up. Take time, but make sure that you are right. Make sure you are always correct. I really appreciate. Very good. Very good. Those who have taken time and got it correct. Very good. I really appreciate. So what will you do? You will first do 1000 times X. Why? Because you want to get rid of this bar first. Sorry. So this will be 3. Sorry. Sorry. What I am doing? Wait a minute. This is 0. Not 0 now any further. 123.3 bar. Correct? Yeah. And then and then what is the next step? You have to do 10 X or 100 X. 100 X. Right? So you have to do 100 X is 12.3 bar. Right? And then subtract the two. You will get 900 X. And this will be 123 minus 12 is 111. Right? And hence most of you have ended up getting this. But X is 111 by 900. And if you cancel this out, this is 37. Isn't it? 37 upon 300. So the answer is B guys. Answer is B. So always reduce it to the lowest. I haven't even looked at anyone. Okay. So here is so mute all don't really switch on your yeah. So next is the leaderboard. Next is the leaderboard. And here is the. There is another way. No problem. You can do that also if you think there is another way. I've got it right. Okay. We'll discuss in the class. It will take some time here. So we'll discuss in the class tomorrow. Anyways, we are meeting. Okay. Right. Is it fine? Is it fine? Let's move on to good uncle. Uncle is also typing uncle. Mr. You're not supposed to answer. You are a. You are a visitor. So. Yeah. Just just checking. Just checking. Just checking. You just whether mathematics or not. You just took away one one position of these my my dear children. These children are more dear to me than you. Okay. So hence. Okay. Don't take away their position. Okay. Anyways. Next. Never mind. Uncle sir also is trying his luck with mathematics. He is brilliant person. But then. I think he's inadvertently pressed the button. Okay. Here is the next question. Now things are going to be a little difficult guys. So stay. Stay calm. Stay calm. Don't press any key. Unless you are doubly sure. Stay very very calm and. Calculate and then answer. The bar is on one seven. It's not on two nor on nine. So Monisha is doubly sure. Good. Thanks for keeping my words. Very good. Very good. Chris. You should not go wrong when you go wrong. Even if you're fastest. What is the point? Right. Why? Okay. You now deliberately reduce your rating. So you just. Yeah. Rishabh is infinitely sure. Okay. Very good. Yes. Good. Unmuted. Who? Sunaina is unmuted. How come? Very Sunaina. Sunaina. Sunaina. Sunaina. Sunaina. Sunaina. Yes. Okay. So let's mute her. Oh sorry. This is because my dear don't rush through. Don't rush through. Yeah. So you have to develop that sportsman's this thing where they are very focused on that. Yeah. Mute all. I just passed it. So I think she's in mute now. Is she still on mute mode? Sunaina. No. She's in. Okay. So here is the last three second guys and let me see the answer. Okay. Okay. So yes. Lot many of you. Yeah. See you understand now. Being fastest as the at this stage will not really make much of a difference. But if you're accurate, your confidence level will go up and that will automatically pull your speed. Dear guys. So hence, you know, focus on accuracy right now. So very well done. Okay. I'll explain. Don't worry. I mean, I'm going to explain explain explain. So here is this question. It is very, very easy. Very easy. In fact, why? Because if you have written like this 0.1217 what is this 1271717171717 like that. Okay. Okay. And then this is 0.0917171717171717171717 like that. If you subtract. This part will get eliminated isn't it. So hence you will get, 0.12. 0.2 minus 0.09 is 0.03, so hence it is 3 upon 100, those who have got it really great, those who could not get it, now you take 15 seconds and reflect what happened, because these 15 seconds of reflection will make sure that next time it never happens again, okay? Take just 15 seconds, close your eyes and make a promise to you that next time I will not repeat the same mistake, first find out what was the mistake and then make a promise to yourself that next time it's not gonna repeat it, okay? Thanks those who have got correctly, those who haven't got it correctly, the questions will not be straight forward, going forward also the questions are little twisted, so hence spend time on them, here is the leaderboard, here is the leaderboard, so Mahika is now leading the, yeah, okay? So it is Raghav for your information, the first 500, every question is of 1000 points, so for the entire time, if you eat up all the time that is 100 seconds, if you consume you will get 500 points only, so it's linearly scaled, I hope you got it, right? So if you click on the very next thing, I think 0th second you will get 1000 points, 1000 till 500, still 8, Ankur sir will disappear, don't worry, don't worry about him, so he was answering that means previously as well, okay, yes, yes, correct, in this case 5 points per second, why because it's a 100 second affair, if I do it 120 seconds it will change, okay? Next question guys, next question guys ready, Ankur sir has taken one seat, sad, never mind, here comes the next question, again take your time and solve, this is going to be lengthy, take your time and solve, take your time and solve, there are two approaches to it, we will discuss that, take your time, piece of paper, pen, work it out guys, 0.4 should be very easy to do, 0.37 also very easy to do, you have to be good at taking LCMs and all, or making common denominators, I really thank all of you to adhere to what I suggested and you are taking time and solving, you will do good guys, trust me, so take your time, take a piece of paper, work out the sum and then mark it, then mark it, okay? Very good, take your time, so now 42 seconds, 40 seconds left, take your time, check your calculations, check your calculation, check your calculation, check your calculation, check your calculation, Sunaina you are not supposed to answer here, here, no discussion please, then it destroys the purpose, so the cross thing comes when I hover around any option, then it will show a cross mark, so sorry for that, okay, okay, no problem, no problem Anush, make a promise to yourself that next time you are not going to do it, that is how you improve, okay, here is the, oh my god, so again, clearly C was not the answer and then people have chosen D, oh wow, it has non-terminating, non-repeating decimal representation, that should not be the answer, that should not be the answer, why should that be? That should not be the answer, why? Isn't it rational, both are rational number guys, did we not discuss this, rational plus rational, how can it be irrational, rational plus rational is always rational, isn't it, so this is anyways eliminated, it has non-terminating, non-repeating, which numbers have non-terminating, non-repeating, this is, this is irrational number definition, so this cannot be the option anyways, now 0.4, if you know the direct method, don't you think 0.4 bar is 4 upon 9, agree, disagree, tell me why, if you agree, why all of you, 0.4 is 4 upon 9, we discuss this and what is 0.37, 0.37 is 37 upon 99, 37 upon 99, so hence you make this 9, so it will become 44 or not, 4 or not, I'm telling you the answer, answer is 9 upon 11, okay, so hence if you add this you get 81 upon 99 and 81 upon 99 is 9 upon 11, right Nitya, so that's the pain dear, I know people who have missed the biggest competitions of their life just by one mark, just by one mark, so hence I don't see any one of you going in that way, I can't see actually, so hence I keep on repeating, don't do mistakes, you know, don't do, you know, don't rush through the problem, take your time, if you are 100% correct, all these timing issues will get sorted out, don't worry, here comes the leaderboard, take your time and solve, take your time and solve, yeah, you could do that or you could have eliminated also, but let's carry on, anyways those who have any other, so 81 by 99 is yes, so yes Krish, correct that also, so hence Maika is, Maika followed by Naomi was the fastest in the second round, Raghav, then Vanisha, I don't know, yeah, anyways, so this is the Ankur, stop answering now, you are in the 10th position, okay, and he has got a very good avatar also it seems, okay, he's a policeman, now, okay, anyways, let's go to, so your previous sins are still carrying on, okay, here is the next question, similar question, take your time and then answer, point, these are not general purpose problems or not typical problems which will be there guys, obviously you need to level, you know, raise your level up, so hence I am giving these questions, these are all fabricated questions, I have made them on my own, it's not picked up from any source, so hence lots of thought process has gone, so if you mark it correct, I feel really excited about it, okay, so hence don't waste questions due to haste, so let's, you know, work it out and be, you know, happy and be proud of yourself, work them out, so very good, take your time, no rush, no hurry, no rush, no hurry, 100% accuracy should be the mantra, okay, no worries, I'll explain here, all questions will be explained, don't bother at all, okay, so hence think but, so break the question into two components, convert them one by one and then do the calculation, that's the question, okay, never mind, so in your grade you have only studied about how to represent point 32 bar as, you know, P by Q form and things like that, right, but then the moment I gave you an arithmetic onto it, right, can you see the pace of response has gone down, that means it requires some kind of calculation, right, and then calculation requires some kind of, some patience, so very good, time's up, no worries, here is the breakup, so most of you have got it correct, that's really, I really thank you all, so at almost 40% of them have got it correct, no worries, those who did not understand here is the question, so first of all, we will break this into two components, this is first component and let us call this as second component, let's work them out independently, independently, so hence first is 0.32 bar, can I write x is equal to 0.32 bar and hence I can write this as 100x is equal to 32.2 bar, okay, and 10x, 10 times x is, we have discussed this 3.2 bar, am I right, guys, just confirm, am I right, am I right, confirm, so hence if I subtract them here, so what will happen, 90x is equal to how much, 29, am I right, am I right, so hence I got x is equal to 29 upon 90, first part, first part, second part, y is equal to let's say 0.123 bar, so first is 1000y, 1000y is 123.3 bar and 100y, 100y is 12.3 bar, so hence if you, in fact, if you remember this was in the previous question, it was directly 111 by 900, do you remember this, we had this in the previous question, so you would have picked up that information and plugged it here, so minus 111 by 900 is nothing but 290 by 900, is it it, and now the calculation is super easy, 179 upon 900, isn't it, now clearly, now let's say you don't want to calculate, okay, you don't want to calculate, then what can you do, you can always eliminate these two, you have to pick between these and these right now, yes, mute, mute, mute, mute, mute, so now, oh sorry, yes, so 179 by 900, a little bit of calculation would have given you this, okay, so if you can roughly calculate it is, you know, you have to just divide by 9 and put the zeros and all that, okay, is that okay, clear to everyone, so I want 179 by 900, just a small division and you'll get 0.1898 bar, okay, I have purposefully given this close so that, you know, those who are hurrying fast, right, they will get it wrong, obviously, and this is the type of questions they will put forth in all these, you know, competitive exams or wherever you are, so you're writing olympiades and other things, not the RMO and the PRMO types, but the SFO types you write, right, that's what I have, right, so all our knowledge and everything stays useless if we really don't get it correct, so in Hindi we call it Jhojita Vaisikandar, so hence try to become Sikandar, right, so win it first, everything else later, okay, next, here is the next question now, yes, that's an old movie, yeah, this is the, that is when I was, the movie was released when I was probably 6 or 7 years old, not defined or not possible to calculate is always a good observation but it's not like that, here is the next question, now we are moving to the next geometry topic, stay tuned, if you're not able to view it, I would suggest you just zoom it in a bit, so here is the question, we have done this representation of, I don't want to play with this otherwise I doubt, okay, 100%, no, it's not listening to me, not letting me to zoom it in, anyways, I clicked, what did, grab your phone, I'm sorry, came back, okay, yes, this one is easy, practically microscopic, I know, so wherever you are, you know, looking at it, just zoom it in, I know, just, let's say if you are watching it on a phone, just zoom it in, and if you are on a, this thing, okay, if you are, if you are uncomfortable, I'll show you here, see, this is the, okay, never mind, so whenever that happens, I'll, so now you know the ABCD options, mark your ABCD in your screen, yeah, I'm trying that Raghav but it's not letting me do, some kind of text wrapping is happening, so anything, let it be, right, done, right, so I don't know whether on the other side, what is happening, yes, so there are 23 seconds left, okay, very good, very good, yeah, control plus, plus, I was using that but it's not letting me do that, text wrapping is happening because there's a picture in the listening background, so hence, too late, I marked, okay, here is the answer, so most of you, aha, there are problems, right, people, people have not, yep, why, why people have not able, who wants explanation, X, X, X, X, X, X, okay, so what was the question, now, it will not be that straightforward that I will draw one unit here, one unit there and you have to find root 2, see, pay attention to this, simple geometry and yes, so many people got confused, that was the purpose actually to, you know, make you think, now listen, this is one unit, correct, this is one unit, what is this, this length, two unit, correct, so this hypotenuse will be root 5, agree, disagree, right, Nishant, you could have seen the proportions, this is double anyways, so it could not be root 2 anyways, right, so root 5 and now OB will be equal to OC or not, circle, arc, same radius, is it okay, clear to everyone those who put X, now confirm, right, yes, yes, say yes, say yes, say yes, okay, so all these questions again, I'm again giving you a small suggestion guys, all the next questions will not be straightforward, please, please, please spend time and work it out, you will be able to for sure, if you just pay a little bit of attention, next question please, here is the next question, so try another, yes, but Jhagrav you can always do the method, right, so here is the good Jhagrav you can do, you know, elimination also, so here five more, now there are only, you know, so there are 15 questions in total, we have done eight, seven more and all of them are geometry based, so it should be easy to conclude the quiz, okay, right, next question guys, ready, here is the next question and here, so those, for them I am showing it here, here, this is the question, in the given graph OD is equal to, same, same graph OD is equal to, OD is equal to, OD is equal to, take the time, take the time and the dimensions and units are given, the length of the required things are given, you have to use the grid for your information, measurement of units are given, so use that for your purpose, okay, this is all about how do we represent number line on, oh sorry, numbers on, number line, fair enough, shall I move back to the, all of you have seen this, see, question now, where was the, yeah, so this is 43 seconds still left, so I can show it here, no worries, take your time, so OC was calculated, OB was calculated, BED is given, do invoke Pythagoras' course and solve this problem, it should be easy, right, what happened, Munisha, you kicked it wrong, so here is 17, 13, 12, 11, so almost all of you have answered it, just waiting for timer to get over and 3, 2, 1, here is the answer, so most of you have got it right, very good, anyone who wants an explanation, anyways I'm going to explain it, yeah, X, how many, no problem, see, guys once again, this is 1, this is 2, this is root 5, we did it last time and this is 2, BED is 2, right, this is 90 degrees, so can I not reapply Pythagoras' theorem here, what will this be, root over 2 square plus root over 5 square, correct, no, so hence it is under root 4 plus 5 which is under root 9 which is 3, so OD is 3, where is OD, C, what is the answer then, answer is C, right, is it okay, those who could not understand, now you understand, please confirm so that I can understand that you have understood game theory, right, did you understand now, those who didn't understand that time, so hence only Pythagoras' theorem is going to be applied, so hence don't rush, that's what I'm saying, only Pythagoras' theorem and common sense, that's it, okay, next, leader board, leader board, leader board, okay, here is right, correct Abhishek, that's real, that's the spirit, very good, okay, so hence now, see, people have started taking time, that's really good, so I'm loving it, so here is the table, let's go to next question folks, again take time, it will not be straight forward, so here is the figure, mark your answer in your phone or PC, it will not be straight forward, think about it, what is not working Rishabh, I hope you are able to participate in the quiz, take your time, take your time, see, analyze, use the common knowledge, you know, the knowledge which we have shared, which we have discussed already, it's only that we have twisted the problems a bit, it's not that NCRT based questions, you will not see, actually I have taken this, I got inspired from Ankursar's physics class, so this question is a physics question, converted into a mathematics question, a person moves one unit in the east, takes a left turn, moves two units, how many units, one unit in the north, then takes the right turn, moves, moves one unit in the east direction, how far is from the original position, this was the question, right, this was the question, so person moves one unit, new east, takes a left turn, moves one units, new north, takes the right turn, moves one unit eastwards, where is he, how far he is from the original position, okay, so two, one, four, time's up, oh my god, lots of people have got it correct, I'm really really happy that you could crack it, very good, very good, that's really amazing and inspiring, okay, so here is the question and it was super duper easy, in fact what, at times I challenge my 11th grade people with this question, they also, most of them cannot answer this, because they really do not see through, right, so here is the solution, right, you have to just drop this perpendicular, okay, so one, and this is how much one, right, so in triangle let's say C D E, name it E, so C E O, triangle C E O, chief executive officer is a right angle triangle and hence I can write O C square is equal to O E square plus E C square, isn't it, right, isn't it, right, so hence what is O E, O E is 1 plus 1 2, so this is 2 square and this is E C is 1, because if you see A, this is a square, isn't it, it's a square, it's a square, so hence what would be this, 1 only, right, so hence 1 and 2, so hence 5, so O C, or O C is under root 5, right, so hence O D is nothing but this is the arc, okay, so hence O D is root 5, did you understand guys, did you understand please, please, please correct me, newtol, okay, Hamsika didn't understand once again, see, this is one unit it is given, okay, this is also one unit, why, because A B C E, if you look at A B C E, it's a square, opposite sides of square are equal, so hence this side is also 1, did you understand that, right, so hence the total length of this side of the right angle triangle was 2 and this side of the right angle triangle was 1, so can I find the hypotenuse with 2 and 1, so under root 2 square plus 1 square, that's 5, is that clear give me thumbs up, come on guys, right, so let's go to the next problem, okay, here, where did it go here, right, so here is the next problem, first B and now things will be easier, I hope so, let's go to, great, great going Manisha, very good, Raghav Siddhanth, Rajan, Naomi, Mahika, Vinesh, Bihar, Karun and Rishabh, proud of you guys, proud of all of you actually, so here is the next question, okay, so I will show it here on the screen, so you have to find out A-H, find the length of A-H look very carefully, multiple steps are there, so hence answer very very carefully Angur Pandeshwar says, I don't know these, I never had a mathematics teacher like Tushar sir, do I teach so bad, oh no, I have to just stop teaching it, so how many have answered, let me see, oh 43 people have already answered, that's so exciting, okay, Pramant Pramant, you made it, your Hindi is totally you know messed up, Pratyakshko Pramant, don't try Hindi, Pramal is totally different word, Pramant means that, but something that is evident, you do not require any evidence for that which is so obvious, that's what it's called, typo of the brain, okay, so where is the, oh it's time's up, oh fantastic, so that means now clarity is coming to the mind, okay, so here, anyone who wants an explanation, anyways I'll explain, but for my understanding, all of you understood this anyone X, X, X, X, okay no problem, see guys, see this is one right, start from here, A-B is one, this is one one and one, and then it is root two, so far so good, give me a thumbs up, so far so good it is root two, those who could not understand so far so good, so far so good, root two, right, so root, this is root two, again by Pythagoras theorem, I'm applying only Pythagoras, so this is one, root two and one, what will be A-D, A-D is root three you get that, by same Pythagoras theorem, root three root three, now if it is root three guys, this will be root three what will be root three, A-E, A-E is equal to A-D is equal to root three, is it it, give me your thumbs up, correct, very good, so A-D A-E is root three started, now come to this one so isn't it, this is one, this is again one, so will this not be root two again, if this is root two dear, so don't you think this is root two, so hence total A-H will be what root three plus root two, clear, I hope this is clear, root three plus root two, clear to everyone, any X, any X okay, fantastic, so let's move ahead simple geometry, is it it, is there anything which you don't know only Pythagoras theorem and little bit of length measurement and all that, okay, very good, so here comes the next question, so quickly we'll have to finish this, four questions more are there, so I would like you all to finish this, think and then mark, don't rush, so if you want I can tell you this is one unit, this is one unit, take your time questions are not, which is that, this is two this is two, this is one, so one two, this is, oh I'm sorry, sorry, sorry, my bad my bad, my bad, I misguided you root two, so this is two, yeah, thanks Agro, okay okay, so is the time up, no, still time is going on sorry Krish, I'm really really sorry, yeah, I'm really sorry treat a short field, separate treat, okay I have to bribe you for this now sorry, my mistake I also did not see that but then anyways, okay here is the oh most of you have got it correct only, so let me explain here is the explanation, so two and two, so this is root eight, I hope there is no problem in understanding this root eight, root eight, okay so root eight, and if this is root eight and this is one, so this is clearly three, you get it, yes, so two and two so four plus four, root eight, okay, three more three more, just finishing, okay, two to fifteen, okay root eight, one, this is three, do you agree all of you, three three, right, if this is three and this is two, so what will this be root of three square plus four, which is root of nine plus four thirteen, root of thirteen and root of thirteen clearly is between three square and four square root of, sorry, under root this and under root this is it it, three square, root of three square, is this clear so nine is less than root thirteen, oh sorry, three, three is less than root thirteen, is less than four, so where will this be somewhere here, so what is the answer, B clear to everyone, anyone didn't understand, go ahead if you have a circle which is centered at O and OD is the radius, it will cut somewhere here to the next question, okay yeah that's hard, that's hard, that is what I wanted to highlight, ahaan, that's where people are making mistakes and hints okay, here is the question, so if you cannot see it, this is the question, so we have done this also see radius, Krish, we'll go back to that first do this now, focus on the current question, think and we have done this so finding a, finding the root of a rational number root of a rational number, let me see how many of you have already done this 24, okay good, see this mistake thing is only hurting me, I don't if you get, let's say out of 15, 6 correct, but 6 on 6 6 attempted, 600% correct, I'll be more happy than 15 attempted, 15 attempted and only 6 correct attempt 6 only, but get 6 out of 6, 100% accuracy at this stage, I would prefer that rather than attempting all 15 and getting only 5 or 3 or 2 or 1 or even 10 that's not correct, that's not good yes I will put Raghav, right now you guys have not tasted negative markings so hence I have not purposefully done it, okay, laps, okay so here is the 3, 2, 1, let me see how many of you got it correct very straight forward if you have paid attention to whatever we discussed oh, things have changed yes, I gave you this thing also, some exercise also on this it was so simple, anyways I will explain quickly see, this was 4.45, this one, so this one also is 4.45, is it? radius of the same circle so that means OA and this is 1 unit 1 unit, this is 1 unit, so total is 4.45 into 2 that is 8.9, 8.9 minus 1, so what is the length of OA? 7.9, is it it? 7.9, is it it? and that's what we learned that if you have a, in this process, the entire process which we discussed, this thing is root of 7.9 so this length AD or AE, AE will be root of 7.9, so the answer is A yeah, AE was root of 7 this is why I gave this question, okay, next please you remember this, the next question is based on this only remember this, question number 14 wrong time sir, didn't similar to that, if you remember the previous question you will be able to do this come on, don't make mistake now, TE guys CE, be careful, CE come on, how much time is left? so I have okay 30, okay 35 seconds until voting closes, come on guys you, oh my god what happened? wait, wait, wait, don't worry oh, it's already, sorry so anyways, what is this? which question was this? this was the last question in English, no, so those who have answered, so 62 people have already answered, so no worries yeah educated guess, so let me explain quickly so this was very very easy for those who have already seen this, the last problem so you know that, what is AE? so AE was how much? you know this is root of 7.9 okay, root of 7.9, and this was how much? 4.45 okay, so what is CA guys? CA was 4.45 minus 1, right and then, and then AE is how much? root of 7.9, so answer is answer is very clearly answer CE, I had asked you, CE is how much? CA plus AE, isn't it? and CA is 3.45 and AE is root over 7.9, so what is the answer? right? B okay, so you have guessed it, okay the final answer our final question, or before that the leader board so this is the, oh my god 73 people are on board right now, okay so Manisha is back on top position, leading Draga, close the game, this is the last question guys let me see which school wins, so very close finish maybe, so the last question of the day is this my dear friends and we very very, Hansika after this after this question I'll explain, don't worry buddy just solve this one, solve the final one, try again, oh Jagrava is now working in very very small amount of time, Jagrava I will check your accuracy, think about it think, thinking is the key guess what last question, okay given okay, but then try again very very simple if you really look at it, if you know the process it's very simple, please take care of the values which have been given, okay so what is the status, 33 people, 42 seconds still left, come on guys come on, come on, come on, come on miss click decision, bye come on over, don't miss click come on, so how many, 17, 16 seconds more, I believe now most of you have figured out sir you know Bangla yes, I know Bangla I studied there boss, Bangal land okay, very good very good and time's up and the result is C so most of you have got it correct and I'm really happy but then I'm also equally perturbed and most of you have not got it correct so let me explain the final one, here is the explanation so you have to find out IF here is I, here is F so the entire length you have to find out, so you have to break it up clearly this one was one, so let me just you know, make it a little zoomed in so this is one and this is also one so clearly this is root two and made it the other way around hence IA is root two, very good Krish IA is root two, no doubts about it now what about, what do you wanted to find out IF, so here this one is 4.65 already given then what is this and you know this process was nothing but you could find out FB and FB was nothing but FB, I'm writing here, FB is nothing but under root two into 4.65 minus one, the previous question thingy you would have noticed hence in my centum hours you will see one question linked to the other so if you really pay attention on learning one particular question you will be able to solve the next one, so this is very clearly 9.3 minus one which is under root 8.3, so FB is clearly 8.3, so hence the total will be oh what root of 8.3 sorry I had, oh so there was IF, oh there is some, oh you got the advantage here guys the options are not correct, something is missing what is missing, what is missing, so now let's convert this question, so what is actually IF find the total value of IF, who will tell me the IF value IF value, IF what is IF value, total IF value is how much so if you see total IF value is root two plus 4.65 plus 4.65 minus one plus root of 8.3 is it is it right, is it okay why, because this is root two this is 4.65 this 4 was 4.65 then come back one, so this is 4.65 minus one, this portion is 4.65 minus one and from B to F you know this is nothing but root of 8.3 correct, so this was little complicated last thing I think there was some error in the options, anyways so we will tell me come on who is this, Sunaina is it Sunaina we discussed this now, how to find out root of how to find out root of 8.3 what was our thing you draw this okay, then here start 0, then 8.3 here correct then add one, you remember we did this okay, then what you do you take a midpoint of let's say this is A, this is V, you take the midpoint of OB so this is let's say C and then what you do you draw a circle circle which passes through B correct and then do what draw perpendicular correct so hence AD, AD represents root of 8.3, we did this exercise you did on GOG you remember Sunaina is this clear so hence if you see if you see if you take this here so this is point E, so what is this AE AE is root of 8.3 okay, what is this CE A rather CA is radius and radius was given as 4.65 so it was 4.65 minus 1, why minus 1 because AB was 1 see, AB was 1 so what will this be this will be 4.65 minus 1 is that okay to everyone so hence and there was root 2 here also root 2, so total is root 2 plus 4.65 plus 4.65 minus 1 plus root over 8.3 this is what is represented as point E here okay so here is what is the final so we will not count that so let's go back to this one so hence this is the final leader word so many congratulations to Monisha then Raghav then Rishabh, Nishant, Svijan, Mahika, Siddhant, Rishabh, Nishant, Niyomi, Pooja okay okay okay Krish, never mind we can discuss it in the class tomorrow so it's already late I hope you understood something today we covered the other half of the number system now we will next centaur will be on exponents and indices so please be prepared for that and yes before that if at all my geography quiz is ready we will do a geography quiz guys so open book quiz keep the book in front of you and then mark your answers you have to mine that I will tell you I am preparing the questions right now NCRD NCRD if you want to and if you want to use Google and answer no problem history will also be there don't worry all the all the subjects will be there so you have to mind the data there the questions will not be straight forward it will be you know little pretty yes online books you have NCRD online right download it keep it in front of you keep it in front of you and try whichever resource you want and solve it challenge okay Geo Geo first Geo okay the challenge is you can use any resource whatever you want and any book yes any book anything under you can you know very good Krish very good so you know you can keep open you know any book all under the sun and the question will be given in front of you you have to mark it right okay if you want to team up that's allowed you can team up also so but two of only two people not more than that and you have to put only one one person will play then because otherwise it will be difficult yes Monisha is going to understand an opening book good very good okay okay see you then thanks a lot and what is the learning for the day accuracy accuracy right let's let's for the for some few more weeks let's work on accuracy okay good going guys I really appreciate that you know kept my words and you solve the problems with patience thanks a lot all of you will shine one day thanks a lot bye bye take care good night stay safe see you in Ranagar at SRF care and people tomorrow
