$\textbf{Various Expenditures (in percentage) Incurred in Publishing a Magazine}$

What is the central angle of the sector corresponding to the expenditure incurred on Royalty ?

• A. $15^\circ$
• B. $24^\circ$
• C. $54^\circ$
• D. $48^\circ$

Answer 1

100. 54 degree. 
     Royalty angle = 360 * (15 /100)  = 54 degree .

Answer 2

We know that, $100\% \implies 360^{\circ}$

Then , the central angle of the sector corresponding to the expenditure incurred on Royalty,$15\% \implies \dfrac{360^{\circ}}{100} \times 15 = 54^{\circ}.$

So, the correct answer is $(C).$
