Given,
Fresh fruits contain 63% water.
Fresh fruits contain 20% water.
Now,
Fresh fruit contain 68% of water 100 kg
Fresh fruit have 68 kg of water.
So, dried portion =100-68
=32 kg
In dry fruits have 20% of water
Dried portion =100-20=80%
1 part of dried portion =10080 parts of dry fruits
Also, 32 kg of dried portion =10080×32 kg of fruits
Now,
10080×32=320080=40 kg
 100 kg of fresh fruits has 40 kg of dry fruits.
