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
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.
