MEANING OF PROFIT

When the selling price of an article is higher or greater than the cost price, we have a profit or gain.

Profit = selling price – cost price

 

MEANING OF LOSS

When the selling price is less than cost price we have a loss.

Loss = cost price – selling price

 

EXAMPLE 1

If a clock is bought for $1,145 and sold for $1,170, what is the gain or losss

Solution

Cost price of clock = $1,145

Selling price = $1, 170

Since the selling price is more than the cost price, we have a profit

Profit = $1,170 – $1,145 = $25

 

EXAMPLE 2

By selling a tin of oil for $1,320, a man made a profit of $150. How much did he pay for it?

Solution

Selling price = $1,320

Profit =  $150

Cost price = $1,320 – $150 = $1,170.
