Question

Successive discounts of 20% and 15% are equivalent to a single discount of
1. 35%
2. 17.5%
3. 32%
4. 17%

Answer 1

Correct Answer - Option 3 : 32%

Given:

Discount, (D₁) = 20% and D₂ = 15%

Formula used:

Equivalent discount, D = D1 + D2 – (D1D2)/100

Calculation:

D = D1 + D2 – (D1D2)/100

⇒ 20 + 15 – (20 × 15)/100

⇒ 35 – 3

⇒ 32

∴ The equivalent discount is 32%
