GRE Section 2 Quantitative Exam - Question 8


Ps age is twice Qs age. One year ago, Rs age was exactly half of Ps age at that time.

Show Answer
Correct Answer: AB

Let P's age be 2Q since P's age is twice Q's age. One year ago, P's age would have been 2Q - 1 and R's age would have been (2Q - 1) / 2. This means R's current age is greater than (2Q - 1) / 2 + 1 = (2Q + 1) / 2, which will always be greater than Q's current age as long as Q's age is positive. Thus, the quantity in Column A is greater.

If "R must be older than Q" as you state, then the correct answer is A.
