Question
A vessel is full of 90-liter milk 18 liter taken out and
replaced by water, again 15liter milk is taken out and replaced by water and again 10liter milk is taken out and replaced by water. the amount of milk left after the 3rd replacement is. type-sscSolution
The amount of milk in replaced mixture. =90(1-18/90) (1-15/90) (1-10/90) =90 (4/5) (5/6) (8/9) =160/3 =53.33%
