    B 126 litres Correct Answer Incorrect Answer
    C 132 litres Correct Answer Incorrect Answer
    D 138 litres Correct Answer Incorrect Answer
    E 144 litres Correct Answer Incorrect Answer

    Solution

    Let initial quantity of water be โ€˜nโ€™ litres. So,
    (84 + 36) : (n + 24) = 5 : 3 Or,
    120 : (n + 24) = 5 : 3 Or,
    n + 24 = 72 Or,
    n = 48 Therefore, required quantity of mixture
    = 84 + 48
    = 132 litres
