Fresh grapes contain 70% by weight while dried grapes contain 10% water by weight. What is the weight of dry grapes available from 100 kg of fresh grapes?	Options
A) 18.33 kg
B) 21.50 kg
C) 25.00 kg
D) 33.33 kg
E) 40.39 kg
From the question we know: 100kg * 70% = 70kg of water in the fresh grapes   100kg - 70kg of water = 30kg of non-water mass   We are looking for the weight of the dry grapes (X).   Since the question tells us that 10% of the weight of the dry graps is water and we know that 30kg is non-water mass we can set up the following equation:   X = 1/10(X) + 30kg   9/10(X) = 30kg   X = 33.33 kg   Answer- 33.33 kg
