If a is 63% of x and c is of x, which of the following is the closest equivalent of the ratio of a to c ?
A. 0.236 B. 0.381 C. 0.595 D. 1.68
Explanation: D Since you are never told what x is, and there is no way to find it, plug in for x. Say that x = 100. 63% of 100 is 63, and of 100 is 37.5. The ratio of a to c is . So, = 1.68. To save time, you can ballpark the answer, since a > c and (D) is the only choice greater than 1.
