Answer Posted / punam tiwari
Fresh grapes contain 90% of their wt as water, alrite. so
wt of water in fresh 20 kg grape would be:
( 20/100) * 90 = 18 kg.
So the dry wt of grapes is 2 kg. This dry wt is not going
to go watever you do with it.
now what would be the wt of dried grapes which contain 20%
of water by wt?
suppose the total wt of dry grapes is W...
W= dry weight of grapes + 20% of W
=> W = 2kg + (W/100) * 20
=> W =2 kg + W/5
=> 2kg = W - W/5 = (5W - W)/5
=> 4W/5 = 2kg
=> W =(2*5)/4 =5/2 kg i.e. 2.5 kg
