1.  Fresh fruit contains 68% water and dry fruit contains 20% water. How much dry fruit can be obtained from 100 kg of fresh fruits ?
A. 20
B. 30
C. 40
D. 50

Answer: Option

Explanation:

The fruit content in both the fresh fruit and dry fruit is the same.
Given,
Fresh fruit has 68% water.so remaining 32% is fruit content. Weight of fresh fruits is 100 kg.

Dry fruit has 20% water.so remaining 80% is fruit content.
Let weight if dry fruit be y kg.
Fruit % in fresh fruit = fruit% in dry fruit
∴ (32/100) x 100 = (80/100 ) x y

∴ We get, y = 40 kg
