Fresh grapes contain 80 percent water while dry grapes contain 10 percent water. If the weight of dry grapes is 250 kg what was its total weight when it was fresh ?

A. 1000 kg

B. 1100 kg

C. 1125 kg

D. 1225 kg

Answer: Option C

Solution(By Examveda Team)

Quantity of pulp in fresh grapes = Quantity of pulp in dry grapes
= (100 - 10)% of 250 kg
= 90% of 250 kg
= 225 kg
Let the total weight of fresh grapes be $$x$$ kg
Then,
⇒ (100 - 80)% of $$x$$ = 225
⇒ 20% of $$x$$ = 225
⇒ $$\frac{x}{5}$$ = 225
⇒ $$x$$ = 225 × 5
⇒ $$x$$ = 1125
Hence, total weight of fresh grapes = 1125 kg
