उत्तर
By taking a scale of 1 unit length = 20 thousand we may draw a bar graph of the above data as follows:
- The two age groups which have the same population are 30-44 and 45-59
-
Senior citizens are the persons in the age group either from 60-74 or from 75 or above. Therefore
Number of senior citizens in the town
= 80000 + 40000
= 1 lakh 20 thousand
Hence, the number of senior citizens in the town is 1 lakh 20 thousand.
