100
kg. of fresh fruits have
40
kg. of dry fruits in them.
Explanation:
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
%
.
As such
80
parts of dried portion makes
100
parts of dry fruits
and
1
part of dried portion makes
100
80
parts of dry fruits
and
32
kg of dried portion makes
100
80
×
32
kg. of dry fruits
or
100
80
×
32
=
40
kg. of dry fruits.
Hence
100
kg. of fresh fruits have
40
kg. of dry fruits in them.
