A department reduces its staff from 48 people to 36. What is the percent decrease?

Correct answer to question 71 (Arithmetic Reasoning): 25 percent

Method

The reduction is 12 people, and 12 divided by the original 48 is 0.25, or 25 percent. Dividing by the new figure of 36 gives 33 percent, and 75 percent is the share that remains.
