Answer: Option C

Explanation:

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.
