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

Explanation:-

Quantity of water in 250 kg dry grapes,
= (10 /100) *250 = 25 kg
Then, pulp of grapes = 225 kg
We get 20 kg pulp in 100 kg fresh grapes.
To get 225 kg pulp , we need fresh grapes,
= (100 *225)/20 = 1125 kg.
