Question

Fresh fruit contain 68% of water and dry fruit contain 20% of water. Then how much dry fruits have in 100 kilograms fresh fruits?

Answer 1

`100` kg. of fresh fruits have `40` kg. of dry fruits in them.

Explanation:

As fresh fruit contain 68% of water `100` kilograms fresh fruits, will have `68` kg. of water and hence `100-68=32` kg. of dried portion.

In dry fruits, we have `20%` of water and hence dried portion is `100-20=80%`.

As such `80` parts of dried portion makes `100` parts of dry fruits

and `1` part of dried portion makes `100/80` parts of dry fruits

and `32` kg of dried portion makes `100/80xx32` kg. of dry fruits

or `100/80xx32=40` kg. of dry fruits.

Hence `100` kg. of fresh fruits have `40` kg. of dry fruits in them.
