Question
In a vessel, the ratio of milk to water is 3:2. 40
litres of mixture is taken out and 20 litres of water is added to the remaining mixture so that the quantity of milk in the new mixture is 8 litres more than that of water. Find the initial quantity of the mixture.Solution
Quantity of milk when 40 litres of mixture is taken out = 3x – 40 × 3/5 = 3x – 24 litres
Quantity of water when 40 litres of mixture is taken out = 2x – 40 × 2/5 = 2x – 16 litres
Quantity of water after adding 20 litres = 2x – 16 + 20 = 2x + 4 litres
ATQ:
3x – 24 = (2x + 4) + 8
3x – 24 = 2x + 12
x = 36
Initial quantity of mixture = 5x = 180 litres
