    Question

    A mixture (milk and water) contains 40% milk and rest

    192 litres water. How much milk should be added to the mixture to make the ratio of milk to water in the mixture 5:6?
    A 26 litres Correct Answer Incorrect Answer
    B 30 litres Correct Answer Incorrect Answer
    C 32 litres Correct Answer Incorrect Answer
    D 23 litres Correct Answer Incorrect Answer
    E 35 litres Correct Answer Incorrect Answer

    Solution

    Initial quantity of milk in the mixture = 192 × (0.40/0.60) = 128 litres
    Let the quantity of milk added be ‘x’ litres
    According to the question,
    (128 + x)/192 = 5/6
    => x = 160 – 128
    => x = 32
    Therefore, quantity of milk added = 32 litres
