Draw a bar graph to represent the above information and answer the following question. (Take 1 unit length = 20 thousand)
All persons in the age group of 60 and above are called senior citizens. How many senior citizens are there in the town?

Answer 1

A Bar Graph (also called Bar Chart) is a graphical display of data using bars of different heights.

Based on the above data, a Bar graph can be created as shown below:

The population of age group 60-74 = 80,000

The population of age group 75 and above = 40,000

80,000+40,000 = 1,20,000 senior citizens are there in the town.
