Question

A bookseller sold 500 copies of a book at a profit of 20%. If a book costs him 15 rupees, the selling price of the books is?

• A. 7000 Rs
• B. 8000 Rs
• C. 9000 Rs
• D. 10,000 Rs

Answer 1

The correct option is C

9000 Rs

We have, Cost of one copy = 15 rupees
∴ Cost of 500 copies = (500 x 15) rupees = 7500 rupees
Profit % = 20
∴ Profit = 20% of C.P. = $\frac{20}{100}$ $\times$ 7500 = 1500 rupees
Now, S.P. = C.P. + Profit = 7500 + 1500 = 9000 rupees
