Drying Fruit

Fruit can be preserved through drying to remove excess moisture.

The water content of a certain fruit, by mass, is $70\mathrm{\%}$. Therefore, $30\mathrm{\%}$ of the fruit, by mass, is other material.

When left in the sun to dry, the fruit loses $80\mathrm{\%}$ of its water content, and the amount of other material remains the same.

Rounded to the nearest tenth, what percent of the dried fruit is water?
