Question

The following table shows the export earnings of India (in thousand crore rupees) during five consecutive years.

Year	2010−11	2011−12	2012−13	2013−14	2014−15
Export(in thousand crores rupees)	540	600	750	950	110

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 names of the countries at points taken at uniform gaps.
Step 3: Choose the scale: 1 small division = 10 thousand crore rupees.
Step 4: Then the height of the various bars are:
Export in 2010−11 : $\frac{540}{10}=54\mathrm{small}\mathrm{divisions}$

Export in 2011−12 : $\frac{600}{10}=60\mathrm{small}\mathrm{divisions}$
Export in 2012−13 : $\frac{750}{10}=75\mathrm{small}\mathrm{divisions}$
Export in 2013−14 : $\frac{950}{10}=95\mathrm{small}\mathrm{divisions}$
Export in 2013−15 : $\frac{1100}{10}=110\mathrm{small}\mathrm{divisions}$


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:
