books for Rs 45 each. At what price should he sell each of the remaining books to mal
15% profit on his outlay?

Answer 1

Answer:

A book seller bought 40 books for 1,600.

C.P. of these 40 books = 1600÷40 => Rs 40.

He sold 10 books for Rs 40 each and 1 book for Rs 45 each.

Remaining Books => 29 Books.

S.P. of 10 books = 10 × 40 => Rs 400+45Rs

=> Rs 445 .

Profit Percentage = (Profit / C.P. × 100) %

15% = Let profit be x. / 40 × 400

x= 15/40×400

x=1500

He should sell the books the price of 1500 to gain

a Profit of 15%.

15%.
