Question

Find the single discount equivalent to two successive discounts bod 25% and 15%.​

Answer 1

◆ Answer -

Discount = 36.25 %

● Explanation -

Let x be cost price of an object.

After 25% discount, selling price is -

SP = CP × (100-25)/100

SP = x × 75/100

SP = 3x/4

After 15% discount, selling price is -

SP' = SP × (100-15)/100

SP' = 3x/4 × 85/100

SP' = 51x/80

So effective discount is -

Discount = (CP-SP')/CP × 100

Discount = 100 × (x - 51x/80) / x

Discount = 100 × 29/80

Discount = 36.25 %

Hence, effective discount is 36.25 %.
