While drawing a bar graph, we keep in mind that
1. The width of the bars should be uniform throughout.
2. The gap between any two bars should be uniform throughout.
3. Bars may be either horizontal or vertical.
To represent the given data by a vertical bar graph, we first draw horizontal and vertical axes. Let us consider that
the horizontal and vertical axes represent the years and the population in lakhs respectively. We have to draw 5
bars of different heights given in the table.
At first we mark 5 points in the horizontal axis at equal distances and erect rectangles of the same width at these
points. The heights of the rectangles are proportional to the population in lakhs.
The vertical bar graph of the given data is following:
Note that each bar is of same width and the gap between them is uniform. Make sure that the width of the bars and
the gap between them should not be necessarily same.

S o l u t i o n :
(1) The youngest age-group is 10-15 years. The number of persons belonging to this group is 1400. The oldest age-

persons over those in the oldest group is
(2) The population of the town is 
(3) The number of persons in the age group 60-65 is 800.
(4) The number of persons in the age group 10-15 is 1400 and the number of persons in the age group 30-35 is
1100. Hence the number of more persons in the age group 10-15 than the group 30-35 is 1400 – 1100
(5) The age group of 1200 persons living in the town is 20-25.
(6) The total number of persons living in the town in the age-group 50-55 is 900.
(7) The total number of persons living in the town in the age-groups 10-15 and 60-65 is 1400 + 800 
(8) It is shown from the bar graph that the height of the bars decreases as the age-group increases.
Hence, the population decreases with the increases in the age-group.
Q u e s t i o n : 6
Read the bar graph shown in Fig. 23.10 and answer the following questions:
(i) What is the information given by the bar graph?
(ii) What was the number of commercial banks in 1977?
(iii) What is the ratio of the number of commercial banks in 1969 to that in 1980?
(iv) State whether true or false:
The number of commercial banks in 1983 is less than double the number of commercial banks in 1969.
S o l u t i o n :
(1) The bar graph represents the number of commercial banks in India during some particular years.
(2) The number of commercial banks in 1977 was
(3) The number of commercial banks in 1969 was
The number of commercial banks in 1980 was
Hence, the required ratio is
(4) The number of commercial banks in 1983 was
The number of commercial banks in 1969 was 90. When we multiply this number by 2, it becomes
Clearly, 230 is not less than 180.
Hence the statement is false.
