Question
420 ml of mixture βBβ contains only water and milk
in the ratio of 7:13, respectively. If the quantity of milk in mixture βAβ is 20% more than that in mixture βBβ and equals to 40% of total quantity of mixture βAβ (milk + water), then find the difference between quantities of water in mixture βAβ and mixture βBβ.Solution
Quantity of milk in mixture βBβ = (13/20) Γ 420 = 273 ml Quantity of water in mixture βBβ = (7/20) Γ 420 = 147 ml Quantity of milk in mixture βAβ = 1.20 Γ 273 = 327.6 ml Total quantity of mixture βAβ = 327.6/0.4 = 819 ml Quantity of water in mixture βAβ = 819 β 327.6 = 491.4 ml Required difference = 491.4 β 147 = 344.4 ml
