Example 5: By selling a desert cooler for `6000, the shopkeeper
loses `300. What is the cost price of the desert cooler?

Solution: Given, S.P. of the desert cooler = `6000 and Loss = `300

∴ Cost price = S.P. + Loss

= `6000 + `300 = `6300

Calculation of S.P.

If we have C.P. and profit for an article, then S.P. = C.P. + Profit

If we have C.P. and loss for an article, then S.P. = C.P. – Loss

Example 6: A bookseller bought some books for `4000 and sold

them at a gain of `600. What was the selling price of
the books?

Solution: Given, cost price of the books = `4000

Profit = `600

∴ Selling price = Cost price + Profit

= `4000 + `600 = `4600

Example 7: A trader buys a goat for `1250 and sells it at a loss of
`85. What is the selling price of the goat?

Solution: Given, Cost price = `1250 and Loss = `85

∴ S.P. = C.P. – Loss

= `1250 – `85 = `1165

EXERCISE 5.2

A. Compute the cost price for each of the following.
1. S.P. = `600, Loss = `25

2. S.P. = `2600, Profit = `500

3. S.P. = `48.50, Profit = `7.50

4. S.P. = `4000, Loss = `500

5. S.P. = `20800, Profit = `1200
