Age group | Number of persons |
1-14 | 2 lakh |
15-29 | 1 lakh 60 thousands |
30-40 | 1 lakh 20 thousands |
45-59 | 1 lakh 20 thousands |
60-74 | 80 thousands |
75 and above | 40 thousands |
Answer:
To draw the bar graph, we will use the following steps. Firstly, draw two perpendicular lines, one is horizontal and one is vertical. Along the horizontal line mark 'age-group' and along vertical line mark 'number of persons'. (ii) Now, take scale of 1 unit length = 20000 along the vertical line and then mark the corresponding values. Also, the heights of bars for various groups are as follows:
(iii) Draw bar of equal width and of height calculated in Step (ii) on the horizontal line with equal gap between them. Thus, we get the following bar graph (a) From bar graph, we see that the lengths of bars for age group 30-44 and 45-59 are same, so age group (30-44) and (45-559) have the same population. (b) \[\because \] persons having age 60 or above are called senior citizens. \[\therefore \] Number of senior citizens in the town = Number of persons of age group (60-74) + Number of persons of age 75 and above = 80000 + 40000 = 120000 1-14 \[\frac{200000}{20000}=10\text{units}\] 15-29 \[\frac{160000}{20000}=8\text{units}\] 30-44 \[\frac{120000}{20000}=6\text{units}\] 45-59 \[\frac{120000}{20000}=6\text{units}\] 60-74 \[\frac{80000}{20000}=4\text{units}\] 75 and above \[\frac{40000}{20000}=2\text{units}\]
