    Question

    A shopkeeper claims to incur a loss of 20% but uses a

    weight of 640 grams in place of 1kg   If the CP of the rice is Rs 80/kg , what will be the % of actual gain/loss ?
    A 30% Correct Answer Incorrect Answer
    B 25% Correct Answer Incorrect Answer
    C 24% Correct Answer Incorrect Answer
    D 45% Correct Answer Incorrect Answer
    E none of these Correct Answer Incorrect Answer

    Solution

    ATQ, We can say that 20% is = 20/100 = 1/5 Then C.P will be = 5, and  S.P will be = 5 – 1 = 4 Therefore, (S.P/C.P) = 4/5 Then = (4/5) x (1000/640) = 5/4  Hence, profit % will be = (1/4) x 100 = 25%
