Represent the above information with the help of a bar graph.

Answer

To represent the given data on a bar graph, we should first draw a horizontal and a vertical line. Here, the horizontal line will show the census year and the vertical line will show represent the population. Since 5 values or data are given, we mark 5 points on the horizontal axis at equal distances and will erect rectangles of the same width with their heights proportional to the given data. Also, on the vertical axis, each difference of 10 will represent a population of 10 lakhs.
