Employees of a company have been categorized according to their religions as given below:

Religions Hindu Muslim Sikh Christian Total

Number of workers 420 300 225 105 1080

Draw a pie-chart to represent the above information.

SOLUTION

We know:

Central angle of a component = (component value / sum of component values ×× 360ο)

Here, total number of workers = 1050

Thus, the central angle for each component can be calculated as follows:

Religion Number of workers Sector angle

Hindu 420 420/1050 ×× 360 = 144

Muslim 300 300/1050 ×× 360 = 102.9

Sikh 225 225/1050 ×× 360 = 77.14

Christian 105 105/1050 ×× 360 = 36

Note: The total number of workers is 1050, not 1080.

Now, the pie chat that represents the given data can be constructed
