Question

Employees of a company have been categorized according to their religious as given below:
$\begin{array}{ccccccc}\text{Religious}& \text{Hindu}& \text{Muslim}& \text{Sikh}& Christian& \text{Others}& \text{Total}\\ \text{Number of workers}& 420& 300& 225& 105& 30& 1080\end{array}$
Draw a pie - chart to represent the above information.

Answer 1

Total = 1080
$\begin{array}{ccc}& & \\ & \text{Item}& \text{Central angle of each sector will be}\\ \left(i\right)& \text{Hindu}& =\frac{420}{1080}\times {360}^{\circ }={140}^{\circ }\\ \left(ii\right)& \text{Muslim}& =\frac{300}{1080}\times {360}^{\circ }={100}^{\circ }\\ \left(iii\right)& \text{Sikh}& =\frac{225}{1080}\times {360}^{\circ }={75}^{\circ }\\ \left(iv\right)& \text{Christian}& =\frac{105}{1080}\times {360}^{\circ }={35}^{\circ }\\ \left(v\right)& \text{Others}& =\frac{30}{1080}\times {360}^{\circ }={10}^{\circ }\\ & & {360}^{\circ }\end{array}$
Now draw a circle and divided it into sectors having the above central angles as shown in the figure.
