GMAT: Data Sufficiency 5

[jamertot007]

Q24 can be solved and the answer is B. The first question is an inequality but the second is not. It states that 700x=280 which will give you an exact value instead of a range like question 1.

Sal, it's because of your teachings that I was able to catch your mistake on Q24. I greatly appreciate all the videos. Before watching these videos I would have agreed with your answer for 24.

Thanks for your videos!! They are great! I just found them here on YT and I am enjoying your review sessions.

By the way can you please tell me what book you are referencing.

Thanks again for your videos!!!

Sal is using the GMAT Official Guide 11th edition. There is a 12th edition now available and some of the problems are the same.

Sal, hats off to you for helping GMAT students. You are doing a great service to GMAT / MBA applicants like me, especially since I have been out of touch from Math for a long time... Thanks

exactly,

i totally agree with u.

he makes it really easy on me. i'm just burshing up with his algebra lectures and here just watching and then practicing. i think with his great effort to help us it became a matter of time ti well prepare to write the gmat test

Thanks for your videos but i think Q.24 is wrong. X<0.5 means x can be both 0.3 or 0.1 or anything. Similarly statement 2 is insufficient too. Taking both the statements together you can answer the question.

Pls avoid such mistakes as there have been 750 people as of today who took away a wrong information.

[50np]

Here, statement 1 says x<0.5. But statement 2 says x=0.4.

So statement 2 is sufficent, but statement 1 is not sufficient. So the answer is B.

Strings, you are wrong too. I am just saying that GMAT is very tricky. We all make mistakes. I am still learning. The problem is that we have less than 120 seconds per question and in a hurry, we make mistakes.

[stringsOdeed]

See thats the mistake 50np.. You are wrong. The second statement is written wrong twice in the video. Actually statement 2 says: 700x>280 (Refer official guide pg:279). So this statement actually comes down to x>04.

Hence both statements together are sufficient.

But ofcourse everybody makes mistakes!! I'm just saying - it could be avoided!!!

[50np]

Strings, you are right man! I agree.

I just checked the official GMAC book and statement 2 is ">" not "=" as mentioned in the video.

Ofcourse, you mean "Hence both statements are NOT sufficient!"

I am getting so frustrated with GMAT these days. I scored 530 in my first attempt without preparation. Then I got a letter from a MBA school saying that I would be selected if I scored more than 550. Now, I desperately need to cross 600. I just have a few days left for my GMAT 2nd attempt.

[50np]

Strings, you are right.

Hence both statements together are not sufficent.

Out of the 700+ videos Sal has provided to you for free I wouldn't be lecturing him on his rare mistakes. Even the book is full of errors. Besides, all the answers are included in the book you should be double checking all answers anyways =]

[C33B33]

Umm maybe I'm going crazy but Q24 looks wrong to me. x can't be solved because they are inequalities...1) x<0.5 and 2) x<0.4

Your videos are very helpful! I wish you had these gmat problems before I took the GMAT! Fortunately I'll be taking it again the near future so I'll definitely use your tutorials to guide me :)
