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?​

You can solve this problem with algebra:

90% of the weight of the fresh grapes is water, so 10% is not water.

10% × 20kg = 2kg of totally waterless grapes.

"Dried" grapes contain 20% water. So 80% of the weight of "dried" grapes is not water.

80% × DGW = 2kg, where DGW is the dried grape weight.

So DGW = 2kg / 80%. The equivalent weight in "dried" grapes is 2.5kg.

Hope this helps,
