Explanation

Quantity of milk=2/(3)Quantity of water in it=(60-40)litres=20 litres. New ratio=1 : 2 Let quantity of water to be added further be x litres. Then, milk : water=40/(20+x). Now, 40/(20+x)=[https://www.indiabix.com/_files/images/aptitude/1-sym-imp.gif] 20+x=80 [https://www.indiabix.com/_files/images/aptitude/1-sym-imp.gif] x=60.
