A shopkeeper wants to give a single discount equivalent to two successive discounts of 15% and 10%. What is the single equivalent discount?
Show answer & explanation
Correct answer: B
Explanation
Given:
First discount = 15%
Second discount = 10%
According to the formula:
Equivalent single discount = a + b − (ab / 100)
Equivalent discount = 15 + 10 − (15 × 10 / 100)
= 25 − 1.5
= 23.5
Single equivalent discount = 23.5%
