    In a container, the ratio of milk to water is 9:7. If 32

    litres of water is added, the quantities of milk and water become equal. What is the total quantity of the mixture now?
    A 200 litres Correct Answer Incorrect Answer
    B 193 litres Correct Answer Incorrect Answer
    C 288 litres Correct Answer Incorrect Answer
    D 322 litres Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the initial quantity of milk and water be 9n and 7n litres respectively.

    So,9n = 7n + 32

    Or,2n = 32

    Or, n = 16

    Therefore, final quantity of mixture = 9n + (7n + 32) = 16 × 16 + 32 = 288 litres
