      Question

      A container contains 300 lit of pure milk and P liters

      of water. Ratio of 25% of mixture to the initial quantity of water is 2 : 3 and when Q liters of water is added to it ratio of total mixture to water becomes 5 : 4. Then find the value of P + Q.
      A 1020 Correct Answer Incorrect Answer
      B 1200 Correct Answer Incorrect Answer
      C 1050 Correct Answer Incorrect Answer
      D 1060 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      (300 + P)/4P = 2/3
      900 + 3P = 8P
      P = 180 liters
      And, (180 + Q)/(480 + Q) = 4/5
      900 + 5Q = 1920 + 4Q
      Q = 1020 liters
      Required sum = 1200 liters
