    C 70 lit Correct Answer Incorrect Answer
    D 54 lit Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let total mixture in vessel be Q liters.
    Initial quantity of water in vessel = 0.30Q
    And, quantity of milk in vessel = 0.70Q
    (0.30Q + 40)/0.70Q = 50/50
    15Q + 2000 = 35Q
    20Q = 2000
    Q = 100 l
    Quantity of milk in vessel = 100 × 70/100 = 70 l
