Question
A retailer sells 12 metres of cloth and earns a profit
equal to the cost price of 3 metres of cloth. Find the profit percentage.Solution
ATQ,
Let the selling price of 1 metre cloth be Rs. ‘SP’ and the cost price of 1 metre cloth be Rs. ‘CP’.
ATQ,
12 × SP – 12 × CP = 3 × CP
Or, 12 × SP = 15 × CP
Or, SP/CP = 15/12 = 5/4
Required profit percentage = {(5 – 4)/4} × 100 = 25%
