    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ;
    Initial quantity of milk = (3/8) × 240 = 90 litres

    Initial quantity of water = (5/8) × 240 = 150 litres

    Let the required quantity of milk to be added be 'y' litres.

    So, (90 + y) :150 = 7:10

    Or, 90 + y = 105

    Or, 'y' = 15
