Question

The present population (in lakhs) of six Indian states is given below:

State	Population(in lakhs)
Bihar	1040
Chhattisgarh	260
Jharkhand	330
Madhya Pradesh	720
West Bengal	910
Rajasthan	690

Represent the above data by a bar graph.

Answer 1

The following steps are followed while drawing the bar graph:

Step 1: On a graph paper, draw a horizontal line OX and a vertical line OY, representing the x-axis and y-axis, respectively.
Step 2: Along OX, write the years at points taken at uniform gaps.
Step 3: Choose the scale: 1 small division = 10 lakhs
Step 4: Then the height of the various bars are:
$$\begin{gathered} \mathrm{Population}\mathrm{of}\mathrm{Bihar}=\left(\frac{1}{10}\times 1040\right)=104\mathrm{small}\mathrm{divisions} \\ \mathrm{Population}\mathrm{of}\mathrm{Chhattisgarh}=\left(\frac{1}{10}\times 260\right)=26\mathrm{small}\mathrm{divisions} \\ \mathrm{Population}\mathrm{of}\mathrm{Jharkhand}=\left(\frac{1}{10}\times 330\right)=33\mathrm{small}\mathrm{divisions} \\ \mathrm{Population}\mathrm{of}\mathrm{Madhya}\mathrm{Pradesh}=\left(\frac{1}{10}\times 720\right)=72\mathrm{small}\mathrm{divisions} \\ \mathrm{Population}\mathrm{of}\mathrm{West}\mathrm{Bengal}=\left(\frac{1}{10}\times 910\right)=91\mathrm{small}\mathrm{divisions} \\ \mathrm{Population}\mathrm{of}\mathrm{Rajasthan}=\left(\frac{1}{10}\times 690\right)=69\mathrm{small}\mathrm{divisions} \end{gathered}$$
Step 5: On the x-axis, draw bars of equal width and of heights obtained in step 4 at the points marked in step 2.

The completed bar graph is as shown below:
