Explanation:
Step by step:
1) Kg of mixture from the mixer
It says that crushed fruit is added to the mixer with the sugar and pectin.
The fruit added is 1000 kg

Initial: 1000 kg of fruit with 14 wt% of solids
<em>This amount of solids is constant </em>
Final: The mass of solids is the same but now it represents the 67 wt%
and
3) Jam produced
