Question

The equivalent discount of two successive discounts of 10% and 15% is:

(a) 25%

(b) 20%

(c) 23.5%

(d) 20.5%

Answer: 23.5%

Step-by-step explanation:

Simple compact relation :

A + B + AB/100

Since these are discounts, both Ac& B are negative.

-10 + (-15) + (-10 x -15)/100

= -25 + 1.50 = -23.50%

Negative means net discount.
