Grapes are 80% water by weight. When a bushel of grapes dries in the sun for two weeks, it loses 60% of its total weight. All of the weight loss is due to the loss of water. After drying for two weeks, what percentage of the grapes is water by weight? Express your answer to the nearest percent.

Let total weight of grapes==10 kg
8kg==weight of water
2kg ==weight of pulp


2 + w ==4
w ==2 kg - weight of water after evaporation.
8 - 2 ==6 kg in water loss
6/8 ==75% - total loss of water.


2 / 4 ==50% weight of water as a percentage of grapes.
