Problem-Solving and Data Analysis practice question
A coat is reduced by 30%, and the sale price is then reduced by a further 10%. What is the total percent reduction from the original price?
Answer: 37
The price becomes 0.70 × 0.90 = 0.63 of the original, a 37% reduction.
Common wrong answers
- If you answered 27
- 27 subtracts 3 from 30 with no basis.
- If you answered 40
- 40 adds the percents, but the second 10% is taken off the already-reduced price.
- If you answered 63
- 63 is the percent that remains, not the reduction.
