The single discount equivalent to a series discount of 60%, 70% and 80% is:
- 97.6%
- 70%
- 85%
- 95.5%
Correct answer: 97.6%
Solution
After successive discounts of 60%, 70%, and 80%, the price factors are 0.4, 0.3, and 0.2. Their product is 0.024, so the final price is 2.4% of the original. Therefore, the equivalent single discount is 97.6%.
