Question
300 litres of mixture X contains acetone and glycerine
in the ratio 7:8, respectively. 150 litres of the mixture is withdrawn and labelled as mixture Y and 8 litres of acetone is added to it. Find the ratio of glycerine to acetone in mixture Y. MTSolution
Quantity of acetone in mixture Y = 150 × 7/15 = 70 litres Quantity of glycerine in mixture Y = 150 – 70 = 80 litres After addition of 8 litres of acetone, New ratio of glycerine to acetone = 80:(70 + 8) = 40:39
