Question
90 litres of mixture contains water and milk in the
ratio 1:5 respectively. If 24 litres of the mixture is replaced by same quantity of water, then find the ratio of water and milk in the final mixture.Solution
Remaining quantity of the original mixture = 90 β 24 = 66 litres Quantity of water in the final mixture = 66 x (1/6) + 24 = 35 litres Quantity of milk in the final mixture = 66 x (5/6) = 55 litres Ratio of water and milk in the final mixture = 35 : 55 = 7:11
