Quantitative Comparison: Quantitative Comparison Practice MCQ

Question Statement:

Column A Column B
a and b are integers.
a2 = b3
ab

Quantity A is greater.
Quantity B is greater.
The two quantities are equal.
The relationship cannot be determined from the information given.

Explanation:

Correct Answer: D

Try different integers for a and b that satisfy the equation a2 = b3 such as a = 8 and b = 4. These numbers satisfy the equation as 82 = 43 = 64. In this case, Quantity A is greater. Because Quantity B is not always greater nor are the two quantities always equal, choices (B) and (C) can be eliminated. Next, try some different numbers. When choosing a second set of numbers, try something less common such as making a = b = 1. Again, these numbers satisfy the equation provided in the problem. In this case, however, the quantities are equal. Because Quantity A is not always greater, choice (A) can now be eliminated. The correct answer is (D).
