    How much water should be added to the mixture, such that milk constitutes 25% of the resultant mixture.
    A 80 litres Correct Answer Incorrect Answer

    C 72 litres Correct Answer Incorrect Answer
    D 56 litres Correct Answer Incorrect Answer

    Solution

    Quantity of milk in the initial mixture = 0.4 X 120 = 48 litres Since, quantity of milk remained unchanged Therefore, total quantity of the resultant mixture = (48/0.25) = 192 litres Quantity of water to be added = 192 - 120 = 72 litres
