  2. It is clear from the graph, total number of boys in all sections of class VII = Sum of heights of all the bars corresponding to boys in different sections = 15 + 30 + 20 + 20 + 25 = 110
  3. It is clear from the graph that in sections VII A and VII D, the number of girls are greater than the number of boys.
  4. From the graph, it is clear that in section VII B, number of boys is maximum.
