    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.
