    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. ‘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%
