Profit = Selling Price - Cost Price
Profit = N45 - N36
Profit = N9
Profit percentage = (Profit / Cost Price) x 100
Profit percentage = (N9 / N36) x 100
Profit percentage = 25%
Therefore, the profit as a percentage of the cost price is 25%.
A trader bought a radio of N36 and sold it for N45. Express the profit as a percentage of cost price.
