 Okay, good evening everyone. There was some problem from my side so I couldn't post it. Start the class now. Okay, people are joining so let me wait for two minutes. Just let me know whether you can see the screen properly or not. Can you see the screen? Okay, so most of people have joined now. I told you last week that I'll be doing these kind of questions once. So let me do question number six for you. A lot of few people have asked me this question separately that how to solve this kind of question. So as I have already discussed with you that in blood relationship kind of question, one thing which matters a lot is there are two things you have to do in blood relationship kind of questions. Blood relationship, first one is type of relations and second one is gender. Now, why these two things are important because to identify relationship, try to understand. So if I see that A and B are my cousins. Now this particular statement is very ambiguous with respect to the gender of the two persons because this is a relationship. Cousin is a word which is used for both male and female. Now, this is a due to reason like parents. So when I talk about parents, parents is also a word which creates ambiguity whether mother or father. So there are few relationships where identify gender is very, very important. So if I don't siblings, one more word, so siblings, you don't know male or female. So there are few relationships which only gives you the type of relationship. And if gender is not provided, you don't know whether I'm talking about male or female. And that is why it becomes very, very important for a very conspicuous answer that both type of relationship and gender is known. One mistake particularly that people do in this kind of question is that if the name has been given as a male name that suppose I write that Ramesh has two siblings. Akash and Amar. Now looking at the name, all the names by Indian standard looks like a name of a male. But don't make a mistake here in this question. Try to understand just having names Ramesh, Akash, Amar doesn't mean that the person I am talking about in the question is a male. Try to establish that relationship in the question in the given context of the question rather than looking at just the type of names being used in the question and then you solving these questions without even establishing the relationship and gender. So always remember all the questions that I do, I tend to mark whether I know the gender or not and whether I know the relationship or not. So this is, few people have written screen not clear. Is it clear to all others? Is it clear to others screen? I can see it in my mobile, it looks clear. Okay, fine, fine. So I will solve this question and by solving this question I would like to show you how I solve blood relationship question. A and this dollar sign B means A is brother of B. Now when I read this question on and I read this first statement, what I read is A dollar sign B means A is brother of B. If A is brother of B then A is male and relationship is brother of second person. So brother of second person. So wherever this dollar sign is coming, I'll write dollar side first male brother of second. So this kind of sign I make. Then add sign and what about second person? I don't know gender of this person. So I could look at here. So whenever I write a person given in the question, I mark a suffix over here and that suffix is denoted by the gender of that person. If I know the person, I write the gender MF. If I don't know anything, I just cross it so that it is very clear that gender of this person has been identified in the question or not. If it is not identified, then I put this cross and I'm very sure at the end of the question while marking my options that I know the specific gender of this person. So this A dollar B means first person is male and brother of the second person. I don't know the gender of the second person here. That means A is wife of B. So first person would be female and second person relationship would be wife. If A is wife of B, it means that A is wife of B. It means that B is husband of A. So here the relationship had been identified because husband-wife relationship there has to be a male and a female. So if first person is wife, second person has to be male. So that's why I'm writing here male. So A to be brother of B, B can be sister of A, B can be brother of A. That is why I have put this cross sign here. Now if I have a hash sign, the hash sign is saying that A is daughter of B. So first person becomes female and daughter. Now you don't know second person is male or female because both male and female can have a daughter. So second person, I don't know the gender and for star, A is father of B. So it means first person is father of, so it means it would be male. Relationship is a father of B and both male and female can have a father. So I don't know anything about the second person. So if try to understand out of the given equation, it is very much sure that I don't know the gender of the second person in case of three cases, which is of dollar sign, which is of hash sign and which is of star sign. I know that in case of ad, the relationship can be identified by both first and second person, for both first and second person. So try to understand here, now U is father in law of P. So how do you do it? U is father in law of P. So it means that if U has to be father in law, U has to be male. So first of all, U has to be male. Try to understand in these three cases, I don't know what U is. Because when star is there, so T is father of U, T is father of U and W is father of U. So here I cannot identify what U is. So I will just check first option and whether I am getting the answer or not. So U star W is giving me that U is where is star, star means father. So U is father of W. So U becomes male anyway. So T has U is saying me that T is daughter of U and then Q and T is saying me that U is wife of T. So try to understand, is this equation making any sense? Still now whatever I have written, is this making any sense? Just tell me. Tell me. You can write few things. Let me remove this till the time of type and I will solve this question not only by the method by which I have started solving but I will also tell you the trick by which you could have easily identified the option. So look at here. This gives me option A gives me that P at Q is wife of Q. And Q dollar T gives me that Q is brother of P hash U gives me that T is daughter of U. So from here only I think I can find out the relationship between because I know from here that U is male. So U is daughter or T is daughter of U. So I have U here and T is daughter. So I am writing here daughter and T has a Q is brother of T. So try to understand if Q is brother. So for this particular person U, Q would be son and P is wife of Q. So wife here is P. So it means that this lady P is daughter in law for this particular person U who is male. So for P U would be father in law. So answer would be first answer. Now I didn't need to do this guys. You should understand why because try to understand for a relationship of father in law I need to find out first the relationship father in law and I need to prove that the person whom I am proving father in law is proved male by the given question. Now here in these three cases the relationship of U can never be identified. So these three cases can never be my answer relationship of U can't be determined here. So I will not even check first option. I will pick first option and I will move ahead from here. That is why I asked you whether that is making some sense or not. So if this question could have been in front of me I could have looked at this three option. I could have seen here that A is star means A is father of B and I can't know the gender of the second person. This is a cross sign here so I write a cross sign here across U and as I cannot establish the gender out here. So I will not be able to say that U is father in law or mother in law even if I am able to establish the relationship. Hence I will just take option A and move ahead. So that is what the shortcut trick which is used in examination that could have been used over here. So I don't know how many questions I solved. Let me solve one more question of this type and then I will move ahead. Question number eight and nine. I know you have solved this but solve it for two minutes. Question number eight I am getting answer D from a lot of you. I am waiting for other answers. Okay so I have got a lot of answers which are eight D and nine C. I will still like to solve this question and then tell you the answer. So and sign here means P is father of Q. So and I am writing here and first person is male not and sign dollar sign. And second person I don't know the gender. So second person I don't know the gender. So I write here nothing has shine means P is mother of Q. So first person becomes female and this becomes mother and second person again no specific information about gender. And third first third one star means so star means that first person is sister of second person again first person becomes female and second person. I don't have any specific information about gender and I write your sister. So let me solve this question and hash L dollar P star Q and then shows that which of the relationship is Q of N. So let me write here N hash elements where is hash so N hash elements N is mother of L. So an L dollar P means L is father of P and P star Q means and so P star Q means P is sister of Q. So try to understand here N is mother of L. So N would be generation first generation here and then comes L and L is father of P. So there is then there is another generation here and I know that N is female and L is father. So L is male and P is sister. So P is female and P is sister of Q. So this is the same generation so which Q shows which of the relationship of Q of N. So N is grandmother of Q but whether Q is granddaughter or grandson you don't know. So question number eight a lot of you have given me answer D which is a right answer because here I mark this sign which shows that Q is. Grand son or daughter of N. And how do you write how do you know that whether you have to write N is grandmother of Q or Q is grandson daughter of N. So you look at here Q of N. So Q is grandson or granddaughter of N. So this is how you have to represent the data. And as there is ambiguity out here there is no clear answer the answer would be 8D. I'm solving it a little bit slowly because in blood relationship kind of question you should generally go up a little bit slow because people tend to make mistake. So there is one specific doubt that because the signs like in question number nine negative plus and multiply sign is there then plus multiply negative sign is there then negative plus multiply sign is there then negative and percentage sign is there. So in these three options people ask me and a lot of people have asked me whether you have that sir should we apply board mass here or something like that. No this is a blood relationship question and every sign has a meaning these are not mathematical signs which have been used here even though they are mathematical signs the meaning of this mathematical signs have been explained over here. So this is not a question of board mass or something so please don't keep these doubts in your mind. So plus sign means first one in question number nine first one is mother so first one is female and second one mother of second one and then negative sign is there. So first one is brother so male and no idea of this person brother of B so second person and no idea of gender and this is brother third percentage sign is there. So percentage sign gives that is father of B so first one is again father and second one gender no idea and fourth one is multiplication sign and fourth one same as a sister of B so first one is female and sister and no idea about gender of the second person. So anywhere here second person's gender is not out so P is maternal uncle of Q. So I need to check you should know that here I don't know the sign of I mean gender of P here I don't know gender of P written at the last. So I will not check option A and D because I cannot identify maternal uncle men's uncle men's male I cannot say that P is male in these two conditions so I will only check B and C. So also there is one more sign that if plus sign comes the first person becomes male. So here actually I don't need to write anything I know that plus sign if first one is followed by plus sign the person becomes male so you look at here plus sign is here it means that I'll write here P is mother of S. So if P is mother of S P cannot be male so it cannot be maternal uncle so in second second one also cannot be my answer because P over here is female P over here is not male. So answer can only be nine C so that is why I see how I have been eliminating answer so you can eliminate answer very quickly rather than writing it and investing time. So question number nine the only option that I can have is nine C. Okay now let me move to how many of you want to revise few more questions from this sheet in case of blood relationship anyone wants to do it. Do you want to solve last two questions? Okay I'm solving question number 14 for you. There is one general trick so the trick is that generally you assume one person to be yourself in the question and then try to identify the relationship. So in this question so what I do is introducing a girl, Vipin said that her mother is only daughter of my mother-in-law. So if I am Vipin so I am saying that so if I assume myself this is just a trick you can apply this you cannot apply this I write this I and I am Vipin. So now a Vipin is replaced by I it means that I am saying the person who is reading the question is saying that her mother is only daughter of my daughter mother-in-law. So as a person my mother-in-law lost daughter only daughter would be my wife. So this is I and I's mother-in-law's mother-in-law daughter would be wife and I'm saying her mother is only daughter it means that I'm talking about a daughter of this daughter. So I am writing here my wife's daughter so my wife's daughter would be my daughter also. So for my daughter I would be what father so answer here is 14 B. So this is one specific example that you assume one person out there as yourself and then you solve the question. A man said to lady your mother your mother-husband sister is my aunt. So mother-husband means my father mother's husband would be my father my father's sisters is my aunt. How is the lady related to man so your mother's father sister is my aunt. So here am I and my mother's husband sister is my aunt and my aunt is aunt of that man also. So this lady is aunt of this man also. So how am I related to him so it can be only one relationship that my aunt is somebody else aunt. Can be a relationship of cousin can be a relationship of brother or can be a relationship of sister. It can be only first generation relationship. So there is only one thing sister here and no answer as cannot be determined so I take sister and move move ahead. If the answer could have been cannot be determined if the option I could have ticked cannot be determined because you don't know the other person is male or female or cousin or brother. Neither the relationship was identified nor the gender was identified. So why I didn't answer sister because there is no option access that cannot be determined. So that's why I ticked here sister because I knew that it's a first generation relationship. So that's why. So I think you I you have got this. Solve these questions that these questions don't need any specific. You have to identify that on solve first two questions. So quick good good very good. Radhika for most of them screen is not blur. Also as I can see in my YouTube channel I mean I'm also looking at it screen is coming out to be fine. So can you please refresh it or can you reopen it from the link I think it would be fine for you. Question number one and two what is the answer question number one one is to eleven would be equal to two is to twenty two eighteen is to twenty seven. So this is two by three so nine into two nine into three so eleven into two eleven into three. So thirty three would be answer question number three is is question number three is fourteen twenty. And so question number three is fourteen twenty. So this is sixteen the answer would be what can you give me the answer. Let me check the let me check what's the answer you are giving three is a yes good three is answer. So this is fourteen is seven into two and this is seven into three minus one. So this is eight into two. So this one would be eight into three minus one. So this would be twenty three. Now question number four can you solve it. Question number four and five you are giving me answer four B. And you are saying that it's five B. For I've got answer from few of you five I have not got. So you may answer of question number five others. Okay question number five and six. No guys I was this is five square and five square minus one. And if this is twenty four eight. So sorry this is five and five square minus one. So this will be eight and eight square minus one. So this is sixty three. So answer is this. So let's go to question number six here. Question number six answer me. This is a good question. How come you guys are writing six C. Those who are writing six C just give me the logic behind it. What's the logic. Those who are writing who all have written Vanisha has written. Anand has written Neha has written Vaishnavi has written. All of you just give me your this thing. Logic behind six C. No what is this by adding twenty how do you add twenty. Oh twenty three plus twenty. So for that matter try to understand this question. That's why I told in the beginning there is no doubt at twenty to seven. I am not questioning that logic for even a second. So I'm not saying that is right or wrong. So let me discuss this question. This question can be solved by three methods. People can think that it is twenty three plus twenty is equal to fifty three. So they write seven plus twenty is equal to twenty seven. That is one logic. Second logic people give in this question is twenty three into two plus seven is equal to fifty three. So seven into two plus seven is equal to twenty one. So this logic also is not wrong. Third logic that people give out here is that twenty three is an prime number. Fifty three also is a prime number seven also is a prime number. So next number also has to be a prime number. So when you write twenty three to fifty three. So what are the prime numbers here twenty nine thirty one then thirty seven then forty one forty three forty seven. So these are the numbers twenty four twenty five twenty six twenty seven twenty twenty nine thirty thirty one two three four five six seven eight nine ten forty one forty three forty seven. So when I write seven to nineteen let me check. So I write eleven thirteen seventeen. So few people also give this particular option that all numbers are prime numbers. So I don't apply any particular this thing. This question has been framed in a wrong manner over here. If I would have given you options I could have never given you two options out here which is twenty one. If I want you to tick option D I could have never given option twenty one and twenty seven to you. I could have written it twenty eight and twenty two or something like that. Then this question would have been difficult for you so that you could have not identified this. So okay no issues this question was not framed in a good manner. Solve question number seven eight and nine. Sorry. Yeah I know twenty plus not twenty three plus twenty is not fifty three it's forty three. So that logic to anyway does not apply my bad. I went by what they said rather than applying my mind and you look at the repercussion of it. So never do it apply your own brain. This gives a direct correlation between your efficiency and application of your brain. Question number seven C is the right answer. Six plus three is nine. So seven plus three would be ten. So C option seven into four is twenty eight. So two into four would be eight. So this is the answer. So these two were easy questions. That's why I didn't give you much time to solve it. Solve question number nine and ten. Question number nine you have been giving me answer. Few people are giving a few people are giving the D every kind of answer I'm getting. Okay. Let me solve questions. Okay. I'll give you some more time. But people have given me answer right to it. So from 65, how do you get 30? So six into five is 30. So it means it is multiplication of two numbers. So from 44 what do I get four into four 16. So answer is B out here. Now 99 minus 23 is equal to 76. So 24 minus 23 is equal to one. So answer out here is one. So nine D and 10 A. Question number 11 and 12. So 11 C is a right answer though I do have. So why nine is to 27 would not be answer here because three is to one by three. One by three into nine is equal to three. So this is nine times nine into 27. Nine is only 27 is only three times of nine and it could have been written 27 is to nine. Then also I could have understood because here bigger number is coming first here. Also bigger number should come first. So only answer I have here is eight is to one by eight. No other number is here. So and why I'm choosing eight is to one by eight. Three is to one by three gives me that for second number. So denominator square is denominator square multiplied and one by three denominator square is equal to the other number three. So it is one by three into nine is equal to three and same is one by three and denominator square is 64. So I get eight out here. So this logic applies in second question. Sorry, third option. So that's why I'm applying this logic question number 12. The answer would be B 43 and 34. So 43 and 34 has been written in reverse order. So 52 in reverse order would be 25. So that's my answer. So this sheet is done. Let's move to another sheet. So here you have to find out relationship in the one C is right answer. Go to second question. Okay, guys. In second question, it's not poison. It's prison. In second question, that's what that's why I was getting confused in second question. Because the person who takes care of museum is known as curator. So the nobody takes care of poison. I mean, this is a wrong word which has been used here. So second question is prison. So in charge of prison is jail. So answer is the question number C. Question number three, sorry. Three is right answer. Poison, the opposite would be nectar. Your fourth option would be C. Our minutes second. So third position from our is second. So for primary, it will be tertiary. So answer is C. Question number five. So flower Lotus is a flower. So which of the following is bird. So fly is not a kind of bird. Sky is not a kind of word. Nest is not a kind of word. Black is a kind of bird. So answer would be B. Question number six. Very easy question for you guys who have been doing math. Sorry, English properly. Question number six is C. It is Antonin's used here. Death, birth, height, death. Question number seven. Good. Seven answer is B. Again, Antonin's abundance, scarcity, extravagance, majorliness. Question number eight, nine and 10. And question number 10 will tell me whether you are studying, whether you are studying civics or not properly. Question number nine. The answer is A not B. Where you fly. Fly means not staying at your position, changing your position. So water it would be swim. Swim means you are changing your position continuously. Float means you are at one position only. Floating at one position. Float is a wrong answer. Swim is the right answer. Question number 10. So a person can vote when he is of age 18 or more. Lok Sabha member can only be, I mean you cannot be of age below 25 years. So for Lok Sabha, for a person to be a Lok Sabha member, he has to attain the age of 25. So answer here is 10 C. Okay. Let's go to question 1112. Give me answer of question number 11 first. Okay, question number 11, the answer is B. Arya Bhatt was a mathematician and Varah Mitra was an astronomer. So answer is B for question number 11. Hunger is related to food and thirst is related to water. So answer here is water. So question number 12, the answer is B. And in question number 13, food is poured into stomach. Food is processed in the stomach. Fuel is related to engine. So question number 13, the answer is engine. Question number 14, can you solve? You have 14 C is the right answer. It would be desert. Question number 15 and 16. 15 is B as birds fly snakes' crown. So sorry, 15 is C, not B. I'm sorry, 15 is C as birds fly snakes' crown. So 15 is C. 16 answer is A. It's Antonin, so nothing else out there. Question number 17 and 18. Both question number 17 and 18 options are C. By putting alphabets in correct order, we find words. By putting words in correct order, we find sentences. So answer is sentence. Question number 18 is uses of Antonin. So life, death, hope, despair. Question number 19. Question number 19, answer is D not C. Though D and C both are similar answer. The skin of the fish is known as a scales. So it would be skin men. You can also say that why not feather bird? So it is not option C because it has been written in opposite order. If it would have been feather and bird, if here it would have been written feather, first and then bird, then this would have also been my answer. But it has been written in incorrect order. That's why C is not answer, D is the answer. Now let's go to first read it and then do it. Question number 1, a lot of you are giving me answer C. So answer C looks like a right answer to me. Let's go to question number 2. Here is question number 2. And here is question number 2. So solve question number 2 only. 2a very easy. So water image. This figure is water image of this figure. So I will take water image of this figure. It would be A. Let's go to question number 3. Yes, 3B, there can be only one answer. V, P, O are not matching with this N. So N opposite of N is only U. So this has to be answer 3B. No other option. Question number 4. So what answer you are giving me for question number 4? 4B is wrong answer. This cross sign, how will you justify this cross sign? This cross sign cannot be justified here. 4B is the right answer. This will convert into this. So first of all, the outer figure remains same. And this semicircle is converted into, what do you say? And even if you look here, you try to understand. Look at here. Here I have, if I write it from here, inner most circle is, or the first one, the outer most circle is square. Then second one is triangle. The third one is here. Third one is again smaller square. And fourth one is a circle, or oval, whatever you want to say. If it doesn't look circular, then it's oval. You look at here, in the second figure, first and third figure are coming together. So in second figure, first it is square. And then the third figure here was square. It is becoming second figure here. And third figure is becoming second figure. So it's interchange of these two figures. So try to understand it is, here the first figure is square. So it remains square. Second figure is half circle, semicircle. Third figure is triangle. So here the second figure would be triangle, because it is interchanged between third and second. So second figure would be triangle. The third figure would be semicircle. So it would be something like this. It would be a semicircle. And fourth will, so first and fourth remain same. And it is interchanged between second and third. So that is why oval would be D and not B. Question number five, what's the answer? Question number five, you have been giving, few of you are giving me answer A. And few of you are giving me answer C. So I'll still wait for your answer. Question number five, I'm waiting for the answer, what you have given me. Question number five, I'm not scrolling down, because I didn't get the answers. Now I'm getting the answers. And I'm getting all kinds of answers. A, C, D, everything. Question number five, the, sorry, question. Question number five, the answer is A. Why the answer is A? Because you look at here what is happening. So the shape on the, this shape, it is, look at here what happens. If I turn it 90 degrees, then what will happen? So this goes by one second. This particular shape goes by 90 degree here. This is turned upside down. And the top part, this particular part. So you look at here, this particular part is taken out and it is getting enlased. So this particular part is getting enlased. And this bottom part is upside down. So you look at here, this is 90 degree left-hand side. This is upside down. Then enlargement of this. So this becomes a square and then this goes upside down. So what happens over here is then this particular figure would be, what to do here? 90 degrees. So upside down means this will remain upside down. This will go by 90 degrees. And then enlargement of the, enlargement of this figure. So this particular figure would be white. You see here, this has been white-hand. So this will be white-hand. So this particular figure would be white-hand. So this would be white-hand here. And this would be enlarged. So this has been enlarged. And this will again become, sorry, this would be enlarged and with black color. So this has been enlarged. And this has been white-hand. So answer is C. Question 5 here, answer is C. So solve question number 6. This question is, I was doubtful between C and A. But I rejected A because figure in A would be, this particular figure would be C. Here three figures are coming. You look at here once more I'll explain this question. Here three figures are coming. This figure, this particular, like when this is converted to this, I already have this, I already have this. But from where this third triangle is coming? So this third triangle is coming from here. And it has been white-hand. So try to understand this has been white-hand and taken like this. This has been upside down and this has been taken 90 degrees on this side. So similarly, I will write in this and I will rotate it upside down. I'll take 90 degrees. So one is going 90 degrees, one is upside down. And one is making, getting white-hand. Here it is not getting white-hand. Here it is wrong because no correlation is found here. And here there are only two figures. So that is why I'm selecting C out here. Look at here guys, it is option elimination out here. I know this question is a bit confusing. I'm explaining it time and again. This cannot be my answer because you look at here, the figure out here is there are two, this kind of figure and it is becoming three out here. Here it is only one. This one is getting eliminated, I don't know where. Sorry, this one is getting eliminated, I don't know where. So B cannot be my answer. Indeed, there has to be three figures. So here there are only two figures. These two figures are becoming, two triangles are becoming three triangles. So here two dumbbells have to become either three dumbbells or two dumbbells and one triangle. So here there is only one, here there is only two. So B and D cannot be my answer. Similarly here in A and C, in A and C you look at here, here there is one colored picture, one white end, one colored triangle, one white end triangle and the third triangle is also white end. So it means that this particular triangle is coming out and getting white end. So here also this particular sign, this sign will come out and will get white end which is coming only here in option C and not in option A. That is why I am rejecting option A and I am telling that option C is the answer. So I hope you understood it now. Question number 6. 6D is right option because this is anti-clockwise movement 90 degree from here to here. So anti-clockwise movement 90 degree would be from here to here. So D is my answer. Question number 7. Question number 7, you are giving me answer C. Most of you are giving me answer C. Question number 7, answer C is correct option. So figure is rotated 45 degree here. Clockwise direction. Yes, this goes clockwise direction. So figure would be rotated clockwise direction. So this becomes straight something like this. 7C is right answer. So thank you so much. This ends the class today's portions of the class. Next class, I will try to bring something more to you. And plus if I have time next class, I would like to discuss a few chapters of SAT with you. So till that time, thank you so much for joining. And let's meet next week. Thank you. Thank you so much.
