Question
200 ml of mixture A containing milk and water in the ratio
of 5:3 respectively is mixed with another 200 ml of mixture B containing milk and water in the ratio of 2:6 respectively. Find the ratio of milk to water in the resultant mixture.Solution
Quantity of milk in 200 ml of mixture A = 5/8 ร 200 = 125 ml
Quantity of water in 200 ml of mixture A = 3/8 ร 200 = 75 ml
Quantity of milk in 200 ml of mixture B = 2/8 ร 200 = 50 ml
Quantity of water in 200 ml of mixture B = 6/8 ร 200 = 150 ml
Desired Ratio = (125 + 50):(75 + 150) = 175:225 = 7:9
