    A 40 litres Correct Answer Incorrect Answer
    B 45 litres Correct Answer Incorrect Answer
    C 50 litres Correct Answer Incorrect Answer
    D 60 litres Correct Answer Incorrect Answer

    Solution

    70% water means 30% milk.
    Current quantity of milk = 60 × 3/5 = 36 litres
    New mixture = 36 ÷ 0.3 = 120 litres
    Water in new mixture = 120 – 36 = 84 litres
    Water in old mixture = 60 – 36 = 24 litres
    Water to be added = 84 – 24 = 60 litres
