Need to add `60Ltr of Water`

The total mix is 60Ltr, which has 2:1 ratio of Milk and water.
Thus,
It contains 40Ltr. Milk and 20Ltr. Water.

Now to make the ratio of 1:2, we need to add water which doubles the current contain of 40Ltr milk
So we need 80 Ltr. of water which shows 1:2. we have 20Ltrs already, so need to add 60Ltr. of water more.

60:40+20 i.e. 2:1
to make it 1:2 we need to add 60l of water.
120:40+80 i.e. 2:1

Quantity of milk = (60)*2/3 litres = 40 litres.
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=1/2
20 + x = 80
x = 60.
Quantity of water to be added = 60 litre

60 litres of 2:1 milk-to-water is 40 liters of milk to 20 liters of water. If you add 60 liters of pure water, then you have 40 liters of milk to 80 liters of water, or a 1:2 milk-to-water ratio....
