Question
400 litres of mixture βAβ contains milk and water in
it. If mixture βAβ is mixed with 500 litres of mixture βBβ which contains water and salt, then the ratio of quantity of milk, water and salt in the final mixture will be 3:8:4, respectively. Find the difference between quantity of water in mixture βAβ and mixture βBβ.Solution
Total quantity of mixture = 400 + 500 = 900 litres Quantity of milk in final mixture = (3/15) Γ 900 = 180 litres Quantity of water in mixture βAβ = 400 β 180 = 220 litres Quantity of salt in mixture βBβ = (4/15) Γ 900 = 240 litres Quantity of water in mixture βBβ = 500 β 240 = 260 litres Required difference = 260 β 220 = 40 litres
