Question

A number increases from 30 to 45 and then decreases from 45 to 36. What is the difference between the percent of increase and the percent of decrease?

Answer 1

30%

Explanation:

The increase was 15/30 = 50%,

The decrease was 9/45 = 20%.

50% - 20% = 30%

Answer 2

There’s a 30% difference between the percent of increase and percent of decrease. There is a 50% increase when it goes from 30 to 45. And a 20% decrease from 45 to 36.
