GRE- Quantitative Reasoning

QUESTION: 46
Of 60 horses in a stable,
are black,
are white, and
are stallions.

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: A total of 32 horses (20 + 12) are either black or white. That leaves 28 horses of
some other color. A total of 32 horses are stallions. Thus, it is possible that all of the stallions are
either black or white, and that none of the stallions are some other color. (Quantity A = 0.)
However, at least 4 of the stallions must be either black or white. (Quantity B = 4.)
