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

Answer 1

To find out how much profit the trader would make at the same rate on goods which he bought for 42 naira, we need to determine the ratio of the profit to the cost of the shirts.

The ratio of profit to the cost of the shirts is 3.50 naira / 28 naira.

To find the profit on goods bought for 42 naira, we can set up a proportion:

3.50 naira / 28 naira = x naira / 42 naira

Cross multiply:

28 naira * x naira = 3.50 naira * 42 naira

28x = 147 naira

x = 147 naira / 28

x = 5.25 naira

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