A container contains 100 liters of milk, from this container 5 liters of milk was taken out and replaced by water this process was repeated further two times. Then how much milk is now contained by the container? Correct Answer 85.73 L

 

Given:

A container contains 100 liters of milk from this container 5 liters of milk was taken out and replaced by water this process was repeated further two times

Calculation

 

Amount of milk left after 3 operations = 100(1 – 5/100)3

 

Amount of milk left after 3 operations = 100 × 19/20 × 19/20 × 19/20 = 85.73 liters

Hence, 85.73 liters contained by the container.
