stne · Answer

The word OFF would have thrown most people off. In this question OFF = Less

Let Kim's income be  100

Then Joe's income is  25 \%   OFF  ( i.e.  25 \%   LESS  ) Kim's income hence  = 75

Soe's income is  1.2 \%  of  75   = 90

Now  90   is what percent  OFF  Kim's income ? (   90   is what percent  less  Kim's income )

90  is  10\%    OFF  ( less )  100

Hence ans B

Hope it's clear.

Would the gmat use such obscure terminology to try and throw someone off?

Do not worry about this question. Most probably GMAT would not use any language that causes ambiguity and confusion.

Given: Soe's income is 20% more than Joe's income, and Joe's income is 25% off Kim's income.
Asked: What percent off kim's income is Soe's income?

Soe = 1.2 Joe; Soe/Joe = 1.2
Joe = .75 Kim; Joe/Kim = .75

Soe/Kim = 1.2 *.75 = 6/5*3/4 = 18/20 = .9

Soe's income is 10% off Kim's income

IMO B
