Question
Mixture ‘X’ has milk and water in the ratio 7:5.
Mixture ‘Y’ has milk and water in the ratio 3:2. If 60 litres of ‘X’ and 75 litres of ‘Y’ are blended together, what is the ratio of milk to water in the resulting mixture?Solution
ATQ,
Quantity of milk in ‘X’ = (7/12) × 60 = 35 litres
Quantity of water in ‘X’ = (5/12) × 60 = 25 litres
Quantity of milk in ‘Y’ = (3/5) × 75 = 45 litres
Quantity of water in ‘Y’ = (2/5) × 75 = 30 litres
Required ratio = (35 + 45) : (25 + 30) = 80:55 = 16:11
