50kg of solutio contains 10%salt solution.what kg of water has to be evaporated to make the salt content to 12.5%?

• Amount of salt in original mixture=(10/100)*50=5kg
  Water=50-5=45kg
  For new solution let weight of mixture be "x" kg.
  (5/x)*100=12.5
  x=40 Water=40-5=35kg
  So, water to be evaporated=45-35=10kg
