    A 10 lit Correct Answer Incorrect Answer
    B 5 lit Correct Answer Incorrect Answer
    C 8 lit Correct Answer Incorrect Answer
    D 15 lit Correct Answer Incorrect Answer

    Solution

    Ratio of milk to water = 3:1
    Quantity of milk and water = 30 and 10
    Since quantity of water is not changed
    1→ 10 liter
    4→ 40 liters
    Amount of milk added = 40 - 30 = 10 liters
