    C 238 litres Correct Answer Incorrect Answer
    D 240 litres Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the initial quantities of milk and water in the vessel be 7x litres and 5x litres respectively.
    60 litres mixture contains 35 litres milk and 25 litres water.
    According to question:
    7x – 35 = 5x – 25 + 30
    2x = 40
    x = 20
    So the initial quantity of mixture = 12 × 20 = 240 litres
