Question
120 ml of mixture A containing milk and water in the ratio
of 2:1 respectively is mixed with another 120 ml of mixture B containing milk and water in the ratio of 3:5 respectively. Find the ratio of milk to water in the resultant mixture.Solution
Quantity of milk in 120 ml of mixture A = 2/3 Ă— 120 = 80 ml
Quantity of water in 120 ml of mixture A = 1/3 Ă— 120 = 40 ml
Quantity of milk in 120 ml of mixture B = 3/8 Ă— 120 = 45 ml
Quantity of water in 120 ml of mixture B = 5/8 Ă— 120 = 75 ml
Desired Ratio = (80 + 45):(40 + 75) = 125:115 = 25:23
