Various Expenditures (in percentage) Incurred in Publishing a Book

Q1:

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

ANS:A - Biding Cost and Transportation Cost

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°.
