Answer 1

Hint: We will use the mean formula to find the average number of students absent in the month March, April, June, July. From the chart, we will get the number of students absent in the respective months. According to the mean formula, we will add the number of students absent in the respective months and then divide it by the total number of months.

Complete step-by-step solution:
From the chart,
The number of students absent in the month of March is: $4$
The number of students absent in the month of April is: $6$
The number of students absent in the month of June is: $10$
The number of students absent in the month of July is: $12$
Total number of months = $4$
The average number of the students absent in the month March, April, June, July =
$\dfrac{\text{No of students absent in march + No of students absent in april + No of students absent in june + No of students absent in july}}{\text{Total no of months}}$
$ = \dfrac{{4 + 6 + 10 + 12}}{4}$
$ = \dfrac{{32}}{4}$
$ = 8$
Therefore, the average number of students absent in the month March, April, June, July is $8$.
The correct option is option D. $8$

Note: The average is described as the mean value that is the same as the ratio of the sum of the range of a given set of values to the total range of values present inside the set. The average components have many applications each in actual existence. Think if we need to find the common age of men or ladies in a set or common male height in India, then we calculate it by way of including all the values and dividing it by using the range of values.
