Question
A vendor earns a profit equal to the cost price of 8
metres of fabric when selling 40 metres of fabric. Calculate 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,
40 × SP – 40 × CP = 8 × CP
Or, 40 × SP = 48 × CP
Or, SP/CP = 48/40 = 6/5
Required profit percentage = {(6 – 5)/5} × 100 = 20%
