    A vessel contains 280 litres of milk and water in the

    ratio of 9:5. If 20 litres of milk is added to the mixture, then find the ratio of milk to water in the final mixture.

    C 3:2 Correct Answer Incorrect Answer
    D 7:4 Correct Answer Incorrect Answer
    E 8:3 Correct Answer Incorrect Answer

    Solution

    The quantity of milk in the initial mixture = 280 × 9/14 = 180 litres The quantity of water in the initial mixture = 280 - 180 = 100 litres The ratio of milk to water in the final mixture = (180 + 20) : 100 = 200:100 = 2:1
