I agree with hobbit, I thought there was a Typo where B has 35 more than A would make sense here. in which case answer C.
what is the source of this crap question?
answer should be C because it has an infeasible solution.. here goes...
from 1) B=1.35A
from 2) B = A+33 (not 1.33A)
taken together -
hence it is possible to compute A (so should be sufficient, answer C)
but the answer for A is illogical for the question.... according to the equations A=94.2
but A and B were given some candies, so the number should be positive integer not a fraction. this fact is also implied by the stem question... you can't speak of odd/even numbers for non-integers.
in gmat there are no questions with illogical solutions that don't follow a common sense interpretation.
