Fresh grapes contain 68% water while dry grapes contain 20% water. How many kilograms of dry grapes can be obtained from 100 kg of fresh grapes?
A. 50 kg
B. 40 kg
C. 80 kg
D. 32 kg
Answer: Option B
Solution (By JKSSB Mock Tests)
Quantity of pulp in fresh grapes = 100% - 68% = 32%. So, pulp = 32 kg. In dry grapes, pulp is 100% - 20% = 80%. Let dry grapes be D kg. 80% of D = 32 implies D = (32 / 0.8) = 40 kg.
