Question
The ratio of quantity of milk and water in a 300 litres
mixture is 6:4, respectively. On removing 'M' litres of mixture the difference between the quantities of milk and water becomes 50 litres. Find the value of 'M'.Solution
ATQ, After removing 'M' litres of mixture, let quantity of milk and water left be 6x litres and 4x litres, respectively. According to the question, 6x - 4x = 50 Or, 2x = 50 Or, 'x' = 50 / 2 = 25 Therefore, after removal of 'M' litres of mixture, quantity of mixture left = 6x + 4x = 10x = 10 × 25 = 250 litres Therefore, 'M' = 300 - 250 = 50
