GRE- Quantitative Reasoning
C. The quantities are equal;
D. The relationship cannot be determined from the information given.

Answer(s): D
Explanation: In the distribution described in Column B, if the third term is the precise average
(arithmetic mean) of the other two terms, then Quantity A would equal Quantity B (for example, if
the two distributions are {2,4} and {2,3,4}). Otherwise, Quantity B would be greater, since its
middle term deviates from the mean of the other two terms.

QUESTION: 39

A. The quantity in Column A is greater;
B. The quantity in Column B is greater;
C. The quantities are equal;
D. The relationship cannot be determined from the information given.
Answer(s): B
Explanation: The two number series have in common integers 21 through 50. So you can
subtract (or cancel) all of these integers from both sides of the comparison. That leaves you to
compare (19 + 20) to 51. You can now see clearly that Quantity B is greater.
