    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.
    A 18% Correct Answer Incorrect Answer
    B 20% Correct Answer Incorrect Answer
    C 25% Correct Answer Incorrect Answer
    D 32% Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the selling price of 1 metre cloth be Rs. β€˜SP’ and the cost price of 1 metre cloth be Rs. β€˜CP’.

    ATQ,

    16 Γ— SP – 16 Γ— CP = 4 Γ— CP

    Or, 16 Γ— SP = 20 Γ— CP

    Or, SP/CP = 20/16 = 5/4

    Required profit percentage = {(5 – 4)/4} Γ— 100 = 25%
