Question

A single discount equivalent to a discount series 20%, 10%, 10% is

• A. 35.20%
• B. 35.50%
• C. 40%
• D. 45%

Answer 1

The correct option is A 35.20%

Let the selling price be 100

discount of 20% will be=$\frac{20}{100}\times 100=Rs20$

selling price after discount will be 100-20=80

Again discount of 10% will be=$\frac{10}{100}\times 80=Rs8$

selling price after discount will be 80-8=72

Again discount will be 10% on discounted selling price=$\frac{10}{100}\times 72=Rs7.2$

Total discount=(20+8+7.2)=Rs35.2

Single discount percentage will be$\frac{35.2}{100}\times 100=35.20percant$
