Question
What is the single discount rate that is equivalent to
applying three successive discounts of 10%, 15%, and 20%, respectively?Solution
Let the initial amount be Rs. '100x' Amount after three successive discounts = 100x X 0.9 X 0.85 X 0.8 = Rs. '61.2x' So, total discount allowed = {(100x - 61.2x)/100x} X 100 = 38.8%
