If the difference between the two expenditures are represented by 18° in the pie-chart, then these expenditures possibly are

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

Paper Cost - Printing Cost	= (25% - 20%) of the total expenditure
	= 5% of the total expenditure.
