This is a great post!

This is important

A, action is complete where as in B, the tense is indicating that the the scientists are still trying..makes sense?

Bought 11th Edition. It has 800 questions in all. None of them are straightforward questions like most in OG10. My advise as others...Buy it soon!

We need a guru's advice....

Please tell me if you have compared the two. Is there substantial overlap? Thanks

D = symbiosis A = Design solution

A...awkward construction..but my choice

Step 1 85% of 160 is 136..hence No. of Men = 136 No. of women = 24 Let the number of people who left be X Remaining = 160 - X Now 30% of X + 10% of 160-X = 24 (Total women) Solving for X...No of people who left the room is 40 Number left in the room is 120.... No of your answers match :( Please check your question...

Whatever be the fraction (100/5)/10 is 2...(100*1/5)/10...??

Are you sure if the answer choices are correct? 1, 2, 3/2, 5/3, 8/5 seems to be the series???

D for me

C for me...and for God's sake, be nice fellas

Only E gives a clear reason in favor of cable cars and hence weakening the argument that it is a bad idea to introduce cable cars in Machu Pichu

Parallelism E

You should post such messages in the correct GMAT forum. I am sure you will find better response. Best wishes AM4

In which case it is A; since the answer is explicitly given as 5'10'' which aint make no sense

b = 2d ; c = d^2 Hence A and B independently give value of C. Hence D

Let A = 8X + Ra Let B = 8Y + Rb If Ra is equal to Rb then 3Ra = 3Rb and 5Ra = 5Rb; Since (A) and (B) independently deny this; we can conclude that Ra is not equal to Rb. If it were 9a = 9b then it would be a different story. Hence D.

It is 2^4 ie; 16. Thanks Bob!

C(5,3) is right. If India can win the series, so can Yankees and Sox play in the world series:D . Good work all!

Hi Can you please tell me the source of this question? Thanks
