A for me to0

D for me

C for me to

E is ok for me to but can someone point why not B please

worst options e - over 75 % of x in France .... compared with over 33 % in Germany (u compare % with % not % with energy) - out d - change of meaning (just over 333% is more than 33%) - out b - energy derived means produced not spent (change of meaning) - out so it between a and c in a) it can refer to energy produced or to nuclear power so c for me whats the OA pls

D for me, let me know if correct and I shall explain

A for me

C for me to

should be E

Thanks for that Chix Math Forum - Ask Dr. Math according to that and everywhere else I can fine |-1| is undefined Please let me know if GMAT sees this differently, may be one for ERIN or MIKE in that case Thanks for your help Chix

wrong question

D for me how can you define |-1|! in A the only valu where x! = |x-1| is 1! = 0! = 1 if x is 0 the 0! not = |-1| as |-1|! is not defined

C for me

D and A

C it is

My bad A it is

My ans is D reason is provided below Total distance is 250 from A we know 1 train did 140 miles in 2 hours. It does not talk about the other train which could have done 150 miles in 2 hrs from B we know the avg speed of the second train was 55 miles throughout, that does not rule out the possibility of doing 248 miles for the first 2 hours and 2 miles for the remaining time Now when we combine A and B we know A did 140 in the first 2 hours and if B had done over 140 in the first 2 hours then it can still manage to the remaining at a very slow pace and have an average of 55 miles an hour. So D

Imo A

Imo E
