Answer» GIVEN, printed price of a book is Rs. 480. First DISCOUNT % = 10% SELLING price after 1st discount = 480 – 10% of 480 ⇒ Selling price after 1st discount = Rs. 432 Let the 2nd discount% be d. Selling price after 2nd discount = 432 – d% of 432 Given, final selling price = Rs. 367.20 ⇒ 432 – d% of 432 = 367.2 ⇒ 64.8 = d% of 432 ⇒ d = 15 |
