Question
105 ml of mixture βPβ contains milk and water in the
ratio of 4:3, respectively is mixed with 36 ml of mixture βQβ containing milk and water in the ratio of 7:5, respectively. Find the ratio of milk to water in the resulting mixture. STSolution
Quantity of milk in mixture P = 4/7 Γ 105 = 60 ml Quantity of water in mixture P = 3/7 Γ 105 = 45 ml Quantity of milk in mixture Q = 7/12 Γ 36 = 21 ml Quantity of water in mixture Q = 5/12 Γ 36 = 15 ml Desired Ratio = (60 + 21):(45 + 15) = 81:60 = 27:20
