    C 75:49 Correct Answer Incorrect Answer
    D 82:51 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Milk in X = (5/8) × 64 = 40 litres

    Water in X = (3/8) × 64 = 24 litres

    Milk in Y = (4/9) × 45 = 20 litres

    Water in Y = (5/9) × 45 = 25 litres

    Required ratio = (40 + 20) : (24 + 25) = 60 : 49 = 60 : 49
