उत्तर

a. Steps to construct the bar graph are as follows:

Step I: We draw two lines perpendicular to each other on a graph paper and call them horizontal and vertical axes.

Step II: Along the horizontal axis, OX mark the towns and along the vertical axis, OY mark the population.

Step III: We choose a suitable scale to determine the heights of bars. Here, we choose the scale as 1 small division to represent 500.

Step IV: First, we draw the bars for year 2007 and then bars for year 2009 for different towns.

Bars for year 2007 and 2009 are shaded separately and the shading is shown in the top right corner of the graph paper.

b. It is clear from the graph, the population growth of town D was maximum.

c. It is clear from the graph, the population growth of town A was minimum.
