The printed price of a book is Rs. 480. A retailer pays Rs. 367.20 for it. He gets successive discounts of 10% and one other rate. His second rate is:
1). 15%
2). 16%
3). 14%
4). 13%
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
