    C 15 litres Correct Answer Incorrect Answer
    D 11 litres Correct Answer Incorrect Answer
    E 20 litres Correct Answer Incorrect Answer

    Solution

    Quantity of milk in container R = 0.40 × 60 = 24 litres Quantity of water in container R = 0.50 × 40 = 20 litres Let x litres of water is added to the container R. According to the question, 24/(20 + x) = 3/5 Or, 120 = 60 + 3x Or, 3x = 60 Or, x = 20 Therefore, water added to container R = 20 litres
