As fresh fruit contain 68% of water 100 kilograms fresh fruits, will have 68 kg. of water and
hence 100−68=32 kg. of dried portion.
In dry fruits, we have 20% of water and hence dried portion is 100−20=80%.
80 parts of dried portion makes 100 parts of dry fruits and 1 part of dried portion makes 10080 parts of dry fruits and 32 kg of dried portion makes 10080×32 kg. of dry fruits
or 10080×32=40 kg. of dry fruits.
Hence 100 kg. of fresh fruits have 40 kg. of dry fruits in them.
