Fresh grapy 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? `1000 kg` b. `1100\ kg` c. `1125\ kg` d. `1225 kg`

Options

A. 2350 kg
B. 2085 kg
C. 2255 kg
D. 2250 kg

Answer

D

Explanation

(d) Let the weight of fresh grapes be x .
Quantity of water in it `=(80)/(100)xx x=(4x)/(5)`
Quantity of pulp it `=(x-(4x)/(5))=(x)/(5)`
Quantity of water in 500 kg dry grapes `=(10)/(100)xx500=50kg`
`:.` Quantity of pulp in it `=(500-50)=450kg`
`(x)/(5)=450`
`:. x=2250 kg `
