After getting two successive discounts, a book with a list price of Rs. 150 is available at Rs. 105. If the second discount is 12.5%, find the first discount.

Solution

✅ Correct Option: 2

The second discount of 12.5% leaves 87.5% of the intermediate price, so that price is 105/0.875=120105 / 0.875 = 120.

First discount =(150−120)/150×100=20%= (150 - 120)/150 \times 100 = 20\%.
