Answer: (1) 60 litres

Explanation:-
The ratio of the acid and water in a mixture = 2: 1
Total quantity of mixture = 60 litres
Then, the of acid in the mixture = 60 x 2/3
= 40 litres

The, quantity of water in the mixture = 60 x 1/3
= 20 litres

If water 60 litres added, then the ratio will be 2: 1
Then, the new ratio of acid and water = (20 + 60): 40
= 80: 40
= 2: 1

Hence, the answer is (1) 60 litres.
