Question
400 litres of mixture X contains acetone and glycerine
in the ratio 11:14, respectively. 100 litres of the mixture is withdrawn and labelled as mixture Y and 6 litres of acetone is added to it. Find the ratio of glycerine to acetone in mixture Y.Solution
Quantity of acetone in mixture Y = 100 × 11/25 = 44 litres Quantity of glycerine in mixture Y = 100 – 44 = 56 litres After addition of 6 litres of acetone, New ratio of glycerine to acetone = 56:(44 + 6) = 28:25
