Question 66

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?

Solution

Quantity of water in 250 kg dry grapes = $$\frac{10}{100}\times250=25$$ kg

=> Pulp of grapes = 225 kg

Since, fresh grapes has only 20% pulp, => $$20\%\equiv225$$

=> Total weight = $$100\%\equiv\frac{225}{20}\times100=1125$$ kg

=> Ans - (B)
