Question

a watermelon contains 90% water. after 12 hours only 12% water remains in it weight is 50 kg. find the initial weight?​

Answer 1

Answer:

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%∗DriedGrapeWeight=2kg

So Dried Grape Weight =

80%

2Kg

=2.5kg.
