Actual Answer : C

If x was the sum of money, then 7 x/12 was the correct answer. Dividing x by 7/12 makes thing equal to 12 x/7, such that
12 x/7 - 7 x/12 = 95
Or (144 x - 49 x)/84 = 95
Or 95 x/84 = 95
Or x = 84 and hence 7 x/12 = 7 × 84/12 = [spoiler]
49.

But, I cannot bet on the source of this question as it simply doesn't reflect the tang that the official questions do. Remember, an official GMAT PS would have the five choices presented in an order of magnitude, ascending or descending, and the nouns and pronouns used there in the stem would be all European, not from any sub-continent as India or something. Anup is an Indian name, I believe; so it's a made up question by some Indian genius, let me guess who.
