    Question

    A milk seller has a 90-litre mixture of milk and water,

    where water makes up 45% of the total volume. He wants to adjust the mixture so that the amounts of milk and water become equal. However, instead of adding milk, he mistakenly adds the same amount of water. What will be the final ratio of water to milk in the mixture?
    A 2:3 Correct Answer Incorrect Answer
    B 2:1 Correct Answer Incorrect Answer
    C 3:4 Correct Answer Incorrect Answer
    D 1:1 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ;

    Present quantity of water in the mixture = 90 X 0.45 = 40.5 litres

    Present quantity of milk in the mixture = 90 - 40.5 = 49.5 litres

    Quantity of milk to be added = 49.5 - 40.5 = 9 litres

    Required ratio = (40.5 + 9):49.5 = 1:1
