    A container contains 240 lit of pure milk and P liters

    of water. Ratio of 25% of mixture to the initial quantity of water is 5 : 4 and when Q liters of water is added to it ratio of total mixture to water becomes 3 : 1. Then find the value of P + Q.
    A 120 Correct Answer Incorrect Answer
    B 100 Correct Answer Incorrect Answer
    C 50 Correct Answer Incorrect Answer
    D 160 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    (240 + P)/4P = 5/4
    240 + P = 5P
    P = 60 liters
    And, (60 + Q)/(300 + Q) = 1/3
    180 + 3Q = 300 + Q
    2Q = 120
    Q = 60 liters
    Required sum = 120
