Various Expenditures (in percentage) Incurred in Publishing a Book
Which two expenditures together have central angle of 108°?
Biding Cost and Transportation Cost
Printing Cost and Paper Cost
Royalty and Promotion Cost
Binding Cost and Paper Cost
Correct answer is A
Central angle of 108° = ( 108/360 x 100 ) % of the total expenditure
= 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°
