How many liters of pure water should be evaporated(removed) from 160 liters of 12% saline(salt) solution so that the solution that remains is a 20% solution?

• 64 liters
  
  Given ---> In 160 liters 12% is salt solution
  ie, 160*12/100 = 19.2 liters of salt
  
  Let x be the solution that contains 20% salt after evaporation.
  so amount of salt = 20/100 *x
  
  Since the salt content in solution does not change
  20/100*x = 19.2
  x = 96 liters
  
  ie remaining solution is 96 liters
  Therefore liters of pure water evaporated = 160 - 96 = 64 liters
