    4:1, and 240 litres of mixture 'Q' has them in the ratio 5:3. What is the ratio of milk to water when both are mixed?
    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 × (4/5) = 288 litres

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

    Quantity of milk in mixture 'Q' = 240 × (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
