GRE : Quantitative Comparison Problem
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. This is the Quantitative Comparison Problem.Understand the basic mathematical principles behind this problem and other problems.
