Fresh grapes contain 84% water while raisins contain 20% water.How many kg of raisin can be made from 80kg of fresh grapes>

1) 16 kg
2) 18 kg
3) 20 kg
4) 22 kg

• Let the kg of raisin be R.
  
  raisin is nothing but dry grapes.
  
  Here, 84% of 80 kg is water.
  so, 16% of 80 kg will be pulp.
  
  therefore, 16%of 80 kg = (100-20)% of R (since raisin contain 20% water the pulp content in raisin is 100-20=80%)
  
  (16*80)/100=(80/100) R
  R=16 kg.
