Answer 2

The cost price of 5 books is 530

Given:

A book seller sold 50 books for 6500 and earned a profit of 1200.

To find:

The cost price of 5 books.

Solution:

A book seller sold 50 books for 6500 and earned a profit of 1200.

Therefore,

Cost price of 50 books = Selling price - Profit

Selling price = 6500

Profit = 1200

Cost price of 50 books = 6500 - 1200

Cost price of 50 books = 5300

Cost price of 1 book = $\frac{5300}{50}$

Cost price of 1 book = 106

Cost price of 5 books = 5 × 106

Cost price of 5 books = 530
