In a mixture of 120 litres ,the ratio of acid and water is 2:1. If the ratio of acid and water is to be 2:3 , then the amount of water (in lit) to be added to the mixture is

• 80 litres
  
  In 120 litres mixture, quantity of acid=120*(2/3)=80 litres, so water=120-80=40 litres.
  Let 'x' litres of water is added to make the ratio of acid and water 2:3, then 80/(40+x)=2/3
  => x=80
