Numerical: successive discounts MCQ - Practice Questions with Answers

Take the marked price as 100. After a 50% discount, the price becomes 50. A further 10% discount makes it 45. A further 20% discount makes it 36. Thus the customer pays 36 out of the original 100, so the total discount is 64%. A 60% discount would leave the price at 40, not 36. The rates 69% and 72% overstate the reduction because successive discounts are applied on the reduced price, not on the original price every time.
