Hey Shaq, That's a great score. I always thought you would definetly do well. Rather I guessed u may get more than 760+. Well, excellent performance and all the best with U'r apps. If you don't mind will u share u'r target schools ? I am trying my second shot on 28th. Hope to reach 700 mark this time atleast. -CG

Guys, I need to learn basics of tense. I can identify Past, present & future as everyone. But when it comes to Simple Past Past Perfect Present Perfect I am lost. Can anyone pls explain each one of the above using only one sentence and changing the tense as you explain ?

E for parallel.

Will pick B.

It's a Yes or No question... my bad :crazy:

Is this E ? 1) p=r => 1/r = 1/r + r/2 ?? 2) r > 0

Hey Shaq, That was superb. Out of curiosity how did u arrive at this ? what pattern does these letters follow.

Will pick E.

Will pick A. All other assumptions are valid.

Guys, 1. B, 2.C and 3. B or D ?? I have same doubt as gmat168 for 3rd qn. 1) 3x^3 - x = 2 ==> x = 1 any other value ??

Now this is interesting, I just missed the earlier discussions stumbled today on this. Well, I too picked E at first. After reading these posts and Nanda's argument, B does make sense after all. Press does enjoy the limelight :)

Well said Shaq, will be A.

Guys, looks trivial to many here :( But I am not getting this. Can anyone elaborate this ?

Shruti, how wud u get the value of Y/X from b ? it can be any value. We need Only one value Moreover, if we try and combine 1 & 2 we still will not get as Y/X can be +ve or -ve HTH Shree

It is 3/8. For every child couple desires to have it is 1/2 chance of a boy or girl => 1/2^4 Of total children we need exactly 2 boys and 2 girls. => 4C2. hence, 1/2^4 * 4c2 = 3/8. transyt am I correct in understanding this ?
