解决方案：
(i) According to the bar graph, youngest age-group is 10-15 years and the number of persons belonging to this group is equal to 1400.
The oldest age-group, however, is 70-75 years and the number of persons belonging to this group = 300
Calculating, we get,
The percentage of youngest age-group persons compared to those in the oldest group is as below:
1400/300 × 100 = 1400/3
(ii) Total population of the town = 300 + 800 + 900 + 1000 + 1100 + 1200 + 1400 = 6700
(iii) Number of persons belonging in the age group 60 – 65 = 800.
(iv) Number of persons belonging in the age group 10 – 15 = 1400
Number of persons in the age group 30-35 = 1100.
Hence the number of more persons in the age group 10 – 15 than the group 30-35 is 1400 — 1100 = 300.
(v) Age group of the 1200 people living in the town is equal to 20 – 25.
(vi) Total number of persons living in the town in the age-group 50 – 55 is equivalent to 900.
(vii) Total number of persons living in the town in the age-groups 10 -15 and 60 – 65 is equivalent to 1400 + 800 = 2200.
(viii) Since, we can see that the height of the bars decreases as the age-group increases. Therefore, the population decreases with the increases in the age-group, as per the bar graph.

(i) The information depicted by the bar graph is a number of commercial banks in India during same years.
(ii) In 1977, the number of commercial banks were 130.
(iii) Ratio of banks in 1969 to 1980 is equivalent to 90 : 150 = 3:5
(iv) Number of banks in 1983 = 230 and the number of banks in 1969 = 90
∴ Number of banks in 1983 is less than double the number of banks in 1969. Therefore, this statement is false.

(viii)最高分数组的学生人数是多少?
(ix)获得19分以上的学生人数是多少?
解决方案：
(i) Students getting less than 20 marks = 27 + 12 = 39
Cost of 1 work book = ₹5
Therefore, Total cost of 39 books = 39 × 5 = ₹195
(ii) No. of students getting the highest mark group is equivalent to 17
∴ Amount paid at the rate of Rs. 10 to each = 10 x 17 = Rs. 170
(iii) The Lowest mark group = 27
∴ Total number of problems given is equivalent to 27 x 5 = 135

(e)班上身高不足150厘米的学生人数为12。
(f)有14名学生，每个学生的身高超过154厘米。
解决方案：
(i) No. of students having more than height of 149 cm = 17 + 9 + 5 = 31
Therefore, percentage of students having more than height of 149 cm= 31/50 x 100 = 62%
(ii) Total no. of students in the range of maximum height is equivalent to 5
(iii) Total no. of students below the height of 150 cm is equivalent to 7 + 12 = 19
Cost of tonic for each student = ₹55
