A trader made a profit of #3.50 on shirts he bought for 28 naira. How much profit would he make at the same rate on goods which he bought for 42 naira?

Answer 1

To find out the profit at the same rate, we need to calculate the profit as a ratio to the cost of the shirts.

Profit ratio = Profit / Cost of shirts.

Given that the trader made a profit of 3.50 naira on shirts he bought for 28 naira,

Profit ratio = 3.50 / 28 = 0.125

To calculate the profit the trader would make on goods that he bought for 42 naira, we multiply the profit ratio by the cost of the new goods.

Profit = Profit ratio * Cost of new goods

Profit = 0.125 * 42 = <<0.125*42=5.25>>5.25

Therefore, the trader would make a profit of 5.25 naira on goods he bought for 42 naira.
