Question

How can I draw a proportionate bar chart to represent this information? How can I draw a simple bar to represent the information? Where can I draw a pie chart to represent the information?

Answer 1

Given a table of types of personnel and numbers employed

Total personnel is 120

`\begin{gathered} Labourers=54 \\ Operators=29 \\ Supervisor=18 \\ Transportation=19 \\ Total=120 \end{gathered}`

Let bar 1 represent labourers

Let bar 2 represent operators

Let bar 3 represent supervisors

Let bar 4 represent transportation

The bar chart representing the given information is shown below

For the pie chart, we will calculate each angle that the different personnel will occupy.

Pie chart is represented in a circle. The sum of angles in a circle is 360°

`\begin{gathered} For\text{ Labourers} \\ =(54)/(120)*360\degree=162\degree \\ For\text{ Operators} \\ =(29)/(120)*360\degree=87\degree \\ For\text{ supervisors} \\ =(18)/(120)*360\degree=54\degree \\ For\text{ Transportation} \\ =(19)/(120)*360\degree=57\degree \end{gathered}`

Let the first row represent labourers

Let the second row represent operators

Let the third row represent supervisors

Let the fourth row represent transportation
