Fresh grapes contain 60% by weight while dried grapes contain 20% water by weight. What is the weight of dry grapes available from 30kg of fresh grapes? Choose the correct choice from the following options:
A) 10 kg  B) 15 kg  C) 20 kg  D) 25 kg  E) 40 kg
From the question we know: 30kg * 60% = 18 kg of water in the fresh grapes   30kg - 18kg of water = 12kg of non-water mass   We are looking for the weight of the dry grapes (X).   Since the question tells us that 20% of the weight of the dry graps is water and we know that 12kg is non-water mass we can set up the following equation:   X = 1/5(X) + 12kg   4/5(X) = 12kg   X = 15 kg   Answer- 15 kg
