## Detailed Solution – Ratio of milk and water is 2:1

Quantity of milk = (60 x 2/3) litres = 40 litres

Quantity of water = (60 – 40) litres = 20 litres

New ratio = 1:2

Let the quantity of water to be added further be x litres

Then milk:water = (40/20+x)

Now, 1/2 = (40/20+x)

=> 20 + x = 80

=> x = 60

∴ Quantity of water to be added = 60 litres
