The pie chart, given here, shows the various expenses of a publisher in the production of a magazine.

What is the difference between the measures of the central angles of sectors for binding charges and paper cost?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 28.8°.
Central angle =
Where P is the given percentage in the graph.
According to the given pie-chart,
Percentage expense on binding = 18%
Central angle corresponding to binding charges =
⇒ = 64.8°
Percentage expense on paper cost = 10%
Central angle corresponding to paper cost =
⇒ = 36°
Now, required difference = 64.8° - 36°
⇒ 28.8°
Hence the difference between the measures of the central angles of sectors for binding charges and paper cost is 28.8°.
