    Question

    A grandmother intended to distribute Rs. 2400 among her

    three grandchildren—A, B, and C—in the ratio of 5:4:3. However, due to an error, she mistakenly distributed the amount in the ratio of 2:2:1. Determine the difference between the amount B actually received and the amount he was originally supposed to get.
    A Rs. 120 Correct Answer Incorrect Answer
    B Rs. 140 Correct Answer Incorrect Answer
    C Rs. 160 Correct Answer Incorrect Answer
    D Rs. 180 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Amount of money received by B = [2/ (2 + 2 + 1)] × 2400 = Rs. 960
    Amount of money supposed to receive by B = [4/ (5 + 4 + 3)] × 2400 = Rs. 800
    Therefore, required difference = 960 – 800 = Rs. 160
