    D 7:4 Correct Answer Incorrect Answer
    E 8:3 Correct Answer Incorrect Answer

    Solution

    The quantity of milk in the initial mixture = 270 × 5/9 = 150 litres The quantity of water in the initial mixture = 270 - 150 = 120 litres The ratio of milk to water in the final mixture = (150 + 15) : 120 = 165:120 = 11:8
