Question

Following data gives the break up of the cost of production of a book:
$\begin{array}{cccccc}\text{Printing}& \text{Paper}& \text{Binding charges}& \text{Advertisement}& \text{Royalty}& \text{Misellaneous}\\ 30\%& 15\%& 15\%& 20\%& 10\%& 15\%\end{array}$
Draw a pie-diagram depicting the above information.

Answer 1

Total = 100
$\begin{array}{ccc}& & \\ & \text{Item}& \text{Central angle}\\ \left(i\right)& \text{Printing}& =30\%of{360}^{\circ }=\frac{30}{100}\times {360}^{\circ }={108}^{\circ }\\ \left(ii\right)& \text{Paper}& =15\%of{360}^{\circ }=\frac{15}{100}\times {360}^{\circ }={54}^{\circ }\\ \left(iii\right)& \text{Binding charges}& =15\%of{360}^{\circ }=\frac{15}{100}\times {360}^{\circ }={54}^{\circ }\\ \left(iv\right)& \text{Advertisement}& =20\%of{360}^{\circ }=\frac{20}{100}\times {360}^{\circ }={72}^{\circ }\\ \left(v\right)& \text{Royalty}& =10\%of{360}^{\circ }=\frac{10}{100}\times {360}^{\circ }={36}^{\circ }\\ \left(vi\right)& \text{Miscellaneous}& =10\%of{360}^{\circ }=\frac{10}{100}\times {360}^{\circ }={36}^{\circ }\\ & & {360}^{\circ }\end{array}$
Now, we draw a circle and divide it into sectors of above central angles as shown in the figure.
