GRE : Quantitative Comparison Problem
This is the Quantitative Comparison Problem-6.Understand the basic mathematical principles behind this problem and other problems.
Column A : X + 32Y
Column B : Y + 32X
From the given information we can deduct B from A.
A – B =
= (X + 32Y) –(Y + 32X)
= 32Y – Y + X – 32X
= 31Y – 31X
= 31(Y – X)
Without knowing the relative values of X and Y, it is not possible to determine whether this is positive or negative.
SO, it is impossible to compare A and B uniquely.
So, D is the answer.
