Fresh grapes contain 60% water, while dry grapes contain 40% water. How many kgs of dry grapes can be obtained by 60 kg of fresh grapes?

The fruit content in both the fresh fruit and dry fruit is the same.

Let 'p' kgs of dry grapes are obtained from the 60 kgs of fresh grapes

=>  $60 x \frac{40}{100} = p x \frac{60}{100}=> p = 40 \mathrm{kgs}.$

Therefore, 40 kgs of Dry grapes are obtained from 60 kgs of Fresh grapes.
