Correct Answer: So, 60 liters water needs to be added.

Explanation:

Sum of the given ratio = 2 + 1 = 3

Quantity of milk = (60 of $\frac{2}{3}$) = 40 liters

Hence, quantity of water will be = 60 – 40 = 20 liters

Assume. x liters water needs to be added.

According to question, $\frac{40}{x+20}=\frac{1}{2}$

=> x + 20 = 80

=> x = 80 – 20 = 60

x = 60

So, 60 liters water needs to be added.
