When constructing a pie chart for students, they were asked what their favourite fruit is out of apples, bananas and oranges. The person making the pie chart did
not put up the percentage but you can measure and see that the interior angles for
three categories are 130 degrees for apples, 80 degrees for bananas and 150
degrees for oranges. Roughly what percentage of students chose apples as a
favourite food?
