Question
A seller makes a profit equivalent to the cost price of 4
metres of fabric by selling 16 metres of the fabric. Find the percentage profit.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,
16 × SP – 16 × CP = 4 × CP
Or, 16 × SP = 20 × CP
Or, SP/CP = 20/16 = 5/4
Required profit percentage = {(5 – 4)/4} × 100 = 25%
