Question

Fresh fruits contains 68% water where dry fruit contains 20% water. How much dry fruit can be obtained from 100 kg of fresh fruits?

Answer 1

This type of sum can be easily done with the help of ratio, no big calculations are required. and if you force your brain it can be done orally. lets try it.

Fresh Fruit = Water: solid= 68:32=17:8 ;(17+8=25)

Dry Fruit = water : solid =20:80=5:20 ;(5+20=25)

now you can see clearly , If you have 100 Kg of fresh fruit. it means you have 8×4=32 kg of solid part.

and in each 25 kg of dryfruit we have 20 kg of solid part of fruit.

So 32 Kg solid fruit part from the fresh fruit will produce {(25÷20)×32}=40 kg of Dry fruits.

So we will get 40 Kg of dry fruits from 100 kg of fresh fruits.

Answer 2

Answer:

Step-by-step explanation:

The fruit content in both the fresh fruit and dry fruit is the same.

given,fresh fruit has 68% water.so remaining 32%(100-68) is fruit content.weight of fresh fruits is 100kg

dry fruit has 20% water.so remaining 80% is fruit content.let weight if dry fruit be y kg.

fruit % in freshfruit = fruit% in dryfruit

32/100 * 100 = 80/100 * y

we get y = 40 kg

fruit pulp = 40 kg

so with water total amount = 40*100/80 = 50 kg
