1.Fresh Grapes contain 90% water by wt. Dried grapes contain 20% water by %age. What will b wt of
dried grapes when we begin with 20 kg fresh grapes?

• solid weight of fresh grapes = solid weight of dried grapes
  let solid part of dried grapes = X
  
  (1-0.9)*20 = (1-0.2)*X
  0.1*20 = 0.8*X
  X = 2.5kg

• weight of fresh grapes=20*10/100=2kg
  now again 20% water is there so
  left weight will be 2*80/100=1.6kg

• (100-90)% of 20 kg fresh grapes=(100-20)% of x dried grapes
  =>10*20/100=80*x/100
  => x=5/2 or 2.5

• weight of dried grape is 2kg.
  given that in fresh grape 90%water so in 1kg fresh grape 900g water and 100g dried grape.
  so in 20kg fresh grape wt of dried grape is 100*20=2000g ,so dried wt grape is 2kg.
