ATQ, After removing 'M' litres of mixture, let quantity of milk and water left be 7x litres and 3x litres, respectively. According to the question, 7x - 3x = 70 Or, 4x = 70 Or, 'x' = 70 / 4 = 17.5 Therefore, after removal of 'M' litres of mixture, quantity of mixture left = 7x + 3x = 10x = 10 * 17.5 = 175 litres Therefore, 'M' = 400 - 175 = 225
