    Total quantity of mixture = 35 litres and ratio of water and acid is 6 : 1 => Quantity of water = $$frac{6}{(6+1)} imes35=30$$ litres Thus, quantity of acid = $$35-30=5$$ litres Now 5 litres of acid is added to the mixture, => acid = $$5+5=10$$ litres => Ratio of water and acid in the new mixture = $$frac{30}{10}=3:1$$ => Ans - (C)
