Fresh fruit contains 72 % water and dry fruits contains 20 % water. How much dry fruit from 100 kg of fresh fruit can be obtained?

As per the given question ,
We are concerned with solid part of the fruit (pure portion). Assume Q kg of dry fruit is obtained.
∴ Solid part in fresh fruit = Solid part in dry fruit
⇒ 0·28 × 100 = 0·8 × Q
⇒ Q = 35 kg
∴ 35 kg of dry fruit can be obtained from 100 kg fresh fruit.
