Question

Q41) If fresh grapes have 90% water, and dry grapes have 20% water, the weight of dry grapes obtained from 20kg of fresh grapes is.

• A. (a) 3.6 kg
  
• B. (b) 2.4 kg
• C. (c) 3 kg
• D. (d) 2.5 kg

Answer 1

The correct option is D (d) 2.5 kg

Ans:41)(d)
Sol: In 20kg of fresh grapes,
Water=90% =18kg;
Material without water=2kg;
In case of dry grapes,
Water = 20%
The remaining 80% material constitutes 2kg.
If 80%=2kg then 100% = 2.5kg.
Weight of dry grapes=2.5kg
