What quantity of dry fruit can be obtained form 100 kg fresh fruits. If fresh fruit contains 68% water and dry fruit contains 20% water.

40 kg

Note: In a fruit there are two components, one is Water and second is Pulp. In this process qty. of pulp remains same always.

Therefore,

In fresh Fruit :- Water  : Pulp = 68% : 32%

In dry Fruit    :- Water  : Pulp = 20% : 80%

*Qty. of pulp in fresh fruit = Qty. of pulp in dry fruit*

Hence

32% of 100 = 80% of Qty of dry fruit

40 kg = Qty of dry fruit
