Question

Manpreet offers two successive discounts of 12% and 8% on the sale of a sweater to his customers on the occasion of Diwali. What is the equivalent single percentage discount offered by Manpreet?

• A. 20.96%
• B. 19.04%
• C. 19.64%
• D. 20.00%

Answer 1

Answer:

B. 19.04%

Two successive discounts of 12% and 8% are given.

Use the formula for equivalent single discount:
$\text{Single discount} = a + b - \frac{ab}{100}$

Here,
(a = 12), (b = 8)

$= 12 + 8 - \frac{12 \times 8}{100}$
= 20 - 0.96
= 19.04%
Equivalent single percentage discount = 19.04%
