      A 45:47 Correct Answer Incorrect Answer
      B 73:27 Correct Answer Incorrect Answer
      C 66:71 Correct Answer Incorrect Answer
      D 43:57 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      ATQ,

      Quantity of milk in mixture 'P' = 360 ├Ч (4/5) = 288 litres

      Quantity of water in mixture 'P' = 360 - 288 = 72 litres

      Quantity of milk in mixture 'Q' = 240 ├Ч (5/8) = 150 litres

      Quantity of water in mixture 'Q' = 240 - 150 = 90 litres

      Therefore, required ratio = (288 + 150) : (72 + 90) = 438 : 162 = 73 : 27
