Question
By selling 25 metres of cloth, a trader gains a profit
equal to the cost price of 5 metres of the same cloth. What is 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,
25 × SP – 25 × CP = 5 × CP
Or, 25 × SP = 30 × CP
Or, SP/CP = 30/25 = 6/5
Required profit percentage = {(6 – 5)/5} × 100 = 20%
