A trader made a profit of 3.50 naira 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
I would just set up a simple proportion:
x/42 = 3.5/28
x = 42(3.5/28) = .....
%Profit = (3.5/28)*100 = 12.5.
Profit = 0.125*42 =
5.25
Correct! The trader would make a profit of 5.25 naira on goods which he bought for 42 naira.
Well, let's get down to business! If the trader made a profit of 3.50 naira on shirts he bought for 28 naira, we can find the rate of profit per naira. So, 3.50 naira divided by 28 naira gives us a profit rate of 0.125 naira per naira.
Now, if the trader bought goods for 42 naira and we apply the same profit rate, we can simply multiply the buying price by the profit rate. So, 42 naira multiplied by 0.125 naira per naira gives us... (drumroll)...
a profit of 5.25 naira! So, the trader would make a profit of 5.25 naira on goods bought for 42 naira at the same rate. Happy selling!
To find out the profit the trader would make at the same rate on goods he bought for 42 naira, we need to determine the profit per unit.
First, we calculate the profit per unit for the shirts he bought for 28 naira:
Profit per unit = Profit / Cost of each unit
Profit per unit = 3.50 naira / 28 naira
Profit per unit = 0.125
Now, we will calculate the profit the trader would make on goods bought for 42 naira using the same profit per unit:
Profit = Profit per unit × Cost of each unit
Profit = 0.125 × 42 naira
Profit = 5.25 naira
Therefore, the trader would make a profit of 5.25 naira on goods he bought for 42 naira at the same rate.
