Common Information Question: 8/9

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

 Hide Ans

Option(A) is correct

Central angle of $108° =\dfrac{108}{360}×100\%$ of the total expenditure

$= 30\%$ of the total expenditure.

From the pie chart it is clear that:

$\text{Binding Cost} + \text{Transportation Cost:}$

$= (20\% + 10\%) \text{ of the total expenditure}$

$= 30\%$ of the total expenditure.

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