Question

    A vessel contains 120 litres of milk and water in the ratio of 3:1. If 15 litres of milk is added to the mixture, then find the ratio of milk to water in the final mixture.

    A 9:5 Correct Answer Incorrect Answer
    B 7:5 Correct Answer Incorrect Answer
    C 11:6 Correct Answer Incorrect Answer
    D 7:2 Correct Answer Incorrect Answer
    E 8:3 Correct Answer Incorrect Answer

    Solution

    The quantity of milk in the initial mixture = 120 × 3/4 = 90 litres The quantity of water in the initial mixture = 120 - 90 = 30 litres The ratio of milk to water in the final mixture = (90 + 15) : 30 = 105:15 = 7:2
