    ratio of 5:2. If 10 litres of milk is added to the mixture, then find the ratio of milk to water in the final mixture.

    C 11:6 Correct Answer Incorrect Answer
    D 8:3 Correct Answer Incorrect Answer

    Solution

    The quantity of milk in the initial mixture = 210 × 5/7 = 150 litres The quantity of water in the initial mixture = 210 - 150 = 60 litres The ratio of milk to water in the final mixture = (150 + 10) : 60 = 160:60 = 8:3
