Problem-Solving and Data Analysis practice question
Quantity A is 25% greater than quantity B. Quantity B is what percent less than quantity A?
Answer: 20
A = 1.25B, so B = 0.8A, which is 20% less than A.
Common wrong answers
- If you answered 25
- 25 assumes the two percentages are the same.
- If you answered 75
- 75 is B as a percent of A when A = 1.33B, or confuses 'percent of' with 'percent less'.
- If you answered 80
- 80 is B as a percent of A, not the percent less.
