- Calculating Age of the Teacher

Age of Class Without Teacher
Let the sum of ages of 44 students be S years.
Therefore, 44 * 18 = S
S = 792

Age of Class With Teacher
Let the age of the teacher be T years.
Now, the total sum of ages of 45 individuals (44 students + 1 teacher) is (44 * 18) + T = 792 + T
The new average age when the teacher is included is (792 + T) / 45
Given that this is 4 months more than the previous average, we can set up the following equation:
(792 + T) / 45 = 18 + 4/12
(792 + T) / 45 = 18 + 1/3
(792 + T) / 45 = 55/3
3(792 + T) = 45 * 55
2376 + 3T = 2475
3T = 99
T = 33

Calculating Age of the Teacher
Therefore, the age of the teacher is 33 years.
So, the correct answer is Option A) 33 years.
