A discount series of 10%, 20% and 40% is equal to a single discount of:_________?
Correct answer: B. 56.8%
- A. 50%
- B. 56.8%
- C. 60%
- D. 70.28%Everyday Science Quiz
Explanation
Successive discounts leave 90% x 80% x 60% = 43.2% of the original price. Hence the equivalent single discount is 100% - 43.2% = 56.8%; the likely wrong choice is 70%, from adding the three discounts instead of applying each to the reduced price.
