Question

The following graph shows the number of boys of a class in different age groups:

Is it possible to find the total number of boys in the age group 0 - 10 years?Answer in Yes/No.

Answer 1

The given graph is a histogram that shows the grouped frequency distribution of the number of boys in the respective age groups.
For example, the following table shows the data for the first two groups: Age Group (years) Number of Boys

$0\le \text{Age}<5$	$60$
$5\le \text{Age}<10$	$65$

Here, the group $0-5$ years excludes the data for exactly $5$ years boys, if any.
And, the group $5-10$ years includes the data for exactly $5$ years boys, if any.

Similarly, the data for exactly $10$ years boys, if any, is exluded from the group $5-10$ years

Hence, by adding the number of boys in both the groups will result the required number of students.

$\therefore$ It is possible to find the total number of boys in the age group $0-10$ years using the given data.
