Solution:
Given, the figure represents a double bar graph.
(a) We have to find the information depicted by the above double bar graph.
The double bar graph represents the information about the number of girls and boys in different sections of Class VII.
(b) We have to find the total number of boys in all sections of Class VII.
Number of boys in all sections of class VII = 15+ 30 + 20 + 20 + 25=11
(c) We have to find the sections in which the number of girls is greater than the number of boys.
From the graph,
In sections A and D, the number of girls is greater than the number of boys.
(d) We have to find the section in which the number of boys is the maximum.
From the graph,
In section B, the number of boys is maximum
(e) We have to find the section in which the number of girls is the least.
