Question
180 ml of mixture A containing tea and milk in the ratio
of 4:5 respectively is mixed with another 270 ml of mixture B containing tea and milk in the ratio of 2:7 respectively. Find the ratio of tea to milk in the resultant mixture.Solution
Quantity of tea in 180 ml of mixture A = 4/9 × 180 = 80 ml
Quantity of milk in 180 ml of mixture A = 5/9 × 180 = 100 ml
Quantity of tea in 270 ml of mixture B = 2/9 × 270 = 60 ml
Quantity of milk in 270 ml of mixture B = 7/9 × 270 = 210 ml
Desired Ratio = (80 + 60):(100 + 210) = 140:310 = 14:31
