Given,

The total strength of a class = 22

The average marks of 21 students = 44

The marks obtained by the remaining student = 66

To find,

The average marks of the whole class.

Solution,

We can simply solve this mathematical problem using the following process:

Mathematically,

Average of a set of observations

= (sum of all the observations)/(total number of observations)

Now, according to the question;

The average marks of 21 students = 44

=> (sum of the marks obtained by the 21 students)/(21) = 44

=> sum of the marks obtained by the 21 students = 44×21 = 924

Now, according to the question;

The average marks of the whole class

= (sum of the marks obtained by all the 22 students)/(22)

= {(sum of the marks obtained by all the 22 students) + marks obtained by the remaining student)}/(22)

= (924+66)/22

= 990/22

= 45

Hence, the average mark of the whole class is equal to 45.
