Answer:
The age of the teacher is 50 years .
Step-by-step explanation:
The average age of 35 students = 14 years.
Total age
= 35 * 14
= 490.
Average age increases by one (1) year
= 14 + 1
= 15 years.
No. of the persons
= 35 + 1
= 36 persons.
Total age of 36 persons
= 36 * 15
= 540 years .
Age of a teacher
= Total age of 36 persons - Total age of 35 students
= 540 - 490
= 50 years.
∴ The age of the teacher = 50 years.
