    of water. Ratio of 25% of mixture to the initial quantity of water is 3 : 2 and when Q liters of water is added to it ratio of total mixture to water becomes 9 : 4. Then find the value of P + Q.
    A 246 Correct Answer Incorrect Answer
    B 250 Correct Answer Incorrect Answer
    C 256 Correct Answer Incorrect Answer
    D 236 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    (320 + P)/4P = 3/2
    640 + 2P = 4P
    P = 64 liters
    And, (64 + Q)/(384 + Q) = 4/9
    576 + 9Q = 1536 + 4Q
    Q = 192 liters
    Required sum = 256 liters
