Question

grapes are 80% water by weight and raisins are 20% water by weight if we start with 500 grams of grapes and remove enough water to turn them into raisins then what is the weight of the raisins that results​

Answer 1

Answer:

Weight of Resin = 125 gm

Step-by-step explanation:

Grapes are 80% water by weight and raisins are 20% water by weight if we start with 500 grams of grapes and remove enough water to turn them into raisins then what is the weight of the raisins that results​

Grapes = 500 gm

Water = (80/100) * 500 = 400 gm

Other Weight = 500 - 400 = 100 gm

Let say Weight of resulted Resin = R gm

Water = (20/100)R = 0.2R

Other Weight = R - 0.2R = 0.8R

As only water is removed , other weight remains same

=> 0.8R  = 100

=> R = 100/.8

=> R = 125

Weight of Resin = 125 gm
