    Solution

    ATQ,

    Let the amount of milk and water in the original mixture be 4x ml and 3x ml respectively.

    Amount of milk in 105 ml of mixture = 4/7 × 105 = 60 ml

    Amount of water in 105 ml of mixture = 105 – 60 = 45 ml

    According to the question:

    (3x – 45 + 210) = 2.25 × (4x – 60)

    Or, 3x + 165 = 9x – 135

    Or, 6x = 300

    Or, x = 50

    Original quantity of mixture = 7x = 7 × 50 = 350 ml
