20 litres of milk contain 2% water.how much pure milk should be added for water comes down to 1%?

• 2% of 20 litre=20*2/100=.40 litre
  Now
  1%=.40litr
  So 100%=40litre
  Pure milk should be added=40-20=20 litr

• 2% is doble of 1%
  hence 20 liters becomes double =40liters
  hence we added 20 liters of milk.

• 20 litres : intially contains 98%of milk so :98/100*20=19.6 water is 2%so 0.4
  if water comes down to 1% milk must be 99% so:99/100*20=19.8
  so amount of pure milk added must be :19.8-19.6= 0.2 lit
