Which two expenditures together have central angle of 108°?

[A].	Biding Cost and Transportation Cost
[B].	Printing Cost and Paper Cost
[C].	Royalty and Promotion Cost
[D].	Binding Cost and Paper Cost

Answer: Option A

Explanation:

Central angle of 108° =		108	x 100		% of the total expenditure
		360

= 30% of the total expenditure.

From the pie chart it is clear that:

Binding Cost + Transportation Cost	= (20% + 10%) of the total expenditure
	= 30% of the total expenditure.

Therefore Binding Cost and Transportation Cost together have a central angle of 108°.
