Question

The population of Delhi State in different census years is as given below:

Census Year	1961	1971	1981	1991	2001
Population in Lakhs	30	55	70	110	150

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

Answer 1

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 will 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.
