Fresh grapes contain 80 percent water while dry grapes contain 10 percent water. If the weight of the dry grapes is 250 kg what is total weight when it was fresh?
সমাধান
সঠিক উত্তর: Option C
Quantity of water in 250 kg dry grapes = 250 × (10/100)
= 25 kg
Then, pulp of grapes = (250 - 25) kg = 225 kg.
We get 20 kg pulp in 100 kg fresh grapes
To get 225 kg pulp, we need fresh grapes = (100 × 225)/20 kg
= 1125 kg.
= 25 kg
Then, pulp of grapes = (250 - 25) kg = 225 kg.
We get 20 kg pulp in 100 kg fresh grapes
To get 225 kg pulp, we need fresh grapes = (100 × 225)/20 kg
= 1125 kg.
