Question

Fresh fruit contains 72% water and dry fruit contains 20% water. How much dry fruit from 100 kg of fresh fruit can be obtained?

• A. 32 kg
• B. 33 kg
• C. 30 kg
• D. 35 kg

Answer 1

Answer: (D)

35 kg

Fresh fruit contains $72$% water So, $100$ Kgs. of fresh fruits will contain $72$ Kgs. of water and $28$ Kgs. of solid material.

When $100$ Kgs. of fresh fruits are dried, $28$ Kgs. of solid material will remain while a part of the $72$ Kgs. of water will evaporate.

Given that these $28$ Kgs. of solid material will account for $80$% of the overall weight of dried fruits (as only $20$% of the weight in dried fruit is water).

If $80$% of the weight of dry fruits $=28$ Kgs., then $100$% of dry fruits will weigh $\frac{28}{80}\times 100=35$Kg
