Problem-Solving and Data Analysis practice question
A price is increased by 25% and the new price is then decreased by 40%. The final price is what percent less than the original price?
Answer: 25
1.25 × 0.60 = 0.75, so the final price is 25% less.
Common wrong answers
- If you answered 15
- 15 subtracts 40 from 25 as though percent changes added.
- If you answered 65
- 65 adds the two changes.
- If you answered 75
- 75 is the final price as a percent of the original, not the decrease.
