Answer 1

Question :- Fresh fruit contains 80% water and dry fruit contains 20% of water. How much dry fruit can be obtained from 100 kg of fresh fruit ?

(a) 25 kg

(b) 40 kg

(c) 30 kg

(d) 60 kg

Solution :-

Given that, fresh fruit has 80% water.

So,

→ Remaining 20% is fruit content.

and,

→ weight of fresh fruits = 100kg.

Than,

→ weight of fruit content = 20% of 100kg = (20 * 100)/100 = 20 kg. --------- Equation (1)

Now,

→ Dry fruit has 20% water.

So,

→ Remaining 80% is fruit content.

Let us assume that, weight if dry fruit is x kg.

Than,

→ weight of fruit content in dry fruit = 80% of x kg. = (80 * x)/100 = 0.8x kg. ---------- Equation (2)

Now, we know that,

→ Fruit content in fresh fruit = Fruit content in dry fruit .

→ Equation (1) = Equation (2)

→ 20kg = 0.8x kg.

→ Dividing both sides by 0.8

→ x = (200/8)

→ x = 25 kg.

Hence, 25 kg of dry fruit can be obtained from 100 kg of fresh fruit .
