Question

Find the single discount equivalent to two successive discounts of 20% and 10%

• A. 28%
• B. 29%
• C. 30%
• D. 26%

Answer 1

The correct option is A 28%

Let the marked price of an article be $Rs.100$
Then first discount on it $=Rs.20$
Price after discount $=Rs.(100-20)=Rs.80$
Second discount on it $=10\%$ of Rs.$80$
$Rs.(80\times \frac{10}{100})=Rs.8$
Price after second discount $=Rs.(80-8)=Rs.72$
Net selling price $=Rs.72$
Single discount equivalent to given successive discounts $=(100-72)=28\%$
