    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Milk in A = (1/2) × 40 = 20 litres

    Water in A = (1/2) × 40 = 20 litres

    Milk in B = (5/8) × 32 = 20 litres

    Water in B = (3/8) × 32 = 12 litres

    Required ratio = (20 + 20) : (20 + 12) = 40 : 32 = 5 : 4
