Calculation of S.P. and C.P.

When the profit or loss and one out of the selling price and the cost price

are given, we can find the other, i.e., either cost price or selling price.

Calculation of C.P.

When the selling price and profit are given, we subtract profit from the
selling price to find the cost price of an item.

i.e., C.P. = S.P. – Profit

Similarly, when the selling price and loss are given, we add loss to the

selling price to calculate the cost price of an article.

i.e., C.P. = S.P. + Loss

Example 4: A calculator was sold for `650 and the shopkeeper gained
a profit of `75. Find the cost price of the calculator.

Solution: Given, the selling price of the calculator = `650 and profit

= `75

∴ Cost price = Selling price – Profit

= `650 – `75 = `575
