Fresh grapes contain 65% by weight while dried grapes contain 10% water by weight. What is the weight of dry grapes available from 400 kg of fresh grapes?
Choose the correct choice from the following answers:
A) 105.00 kg
B) 115.60 kg
C) 125.00 kg
D) 130.50 kg
E) 155.55 kg
From the question we know: 400kg * 65% = 260kg of water in the fresh grapes   400kg - 260kg of water = 140kg 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 140kg is non-water mass we can set up the following equation:   X = 1/10(X) + 140kg   9/10(X) = 140kg   X = 155.55 kg   Answer- 155.55 kg
