    weight which is 20% less. Find his total percentage gain.
    A 40% Correct Answer Incorrect Answer
    B 45% Correct Answer Incorrect Answer
    C 50% Correct Answer Incorrect Answer
    D 52% Correct Answer Incorrect Answer

    Solution

    Suppose he bought at Rs. x /kg Then, he sells at 112x/100 * 100/80 = 7x/5 per kg Now % profit = (7x/5 – x) * 100/x = 40% Alternate Method: Total percentage profit = (% profit + % less in weight) * 100/(100 - % less in weight = (12 + 20)*100/ (100 – 20) = 40%
