What would be average age of only the students?
Answer: (3) 14 years
The average of 33 students and class teacher in a class = 15 years
Therefore, the total age of all students and teacher in a class = 34 x 15
= 510 years
The teacher’s age = 48 years
Then total age of all students = 510 – 48
= 462 years
The average age of all students = 462/33
= 14 years
Then the average of only the students is 14 years.
Hence, the correct answer is option (3) 14 years.
