Question

Three successive discounts of 20%, 25% and 16 2/3% is equivalent to a single discount of

• A. 50%
• B. 56.67%
• C. 61.67%
• D. 75%

Answer 1

The correct option is A 50%

If x was the initial price, then the final price $=x\times (1-\frac{1}{5})\times (1-\frac{1}{4})\times (1-\frac{1}{6})=\frac{1}{2}x$
The discount percentage = 50%
