Question
Mixture ‘P’ has milk and water in the ratio 5:3
respectively. Mixture ‘Q’ has milk and water in the ratio 4:1 respectively. If 96 litres of ‘P’ and 80 litres of ‘Q’ are combined to create mixture ‘R’, what is the ratio of milk to water in ‘R’?Solution
ATQ,
Quantity of milk in ‘P’ = (5/8) × 96 = 60 litres
Quantity of water in ‘P’ = (3/8) × 96 = 36 litres
Quantity of milk in ‘Q’ = (4/5) × 80 = 64 litres
Quantity of water in ‘Q’ = (1/5) × 80 = 16 litres
Required ratio = (60 + 64) : (36 + 16) = 124:52 = 31:13
