Answer Posted / ranjit kumar
wieght of the fresh grapes of 20kg quantity = 90/100 x 20
=18kg of water.
weight of dried grapes of 20kg quantity =20/100 x20
=4kg of water
weight when fresh grape converts onto dried grapes=90-20
=70%of water is lost
=70/100 x 20
=14kg of water lost
so remaining weight=6kg
actual weight of dried grape=4kg
hence weight=6-4=2kg
