Answer:
50 years
Step-by-step explanation:
average age of 35 students = 14 years
total age = 35 x 14 = 490
average age increased by 1 year = 14 + 1 = 15 years
number of person = 35 + 1 = 36
total age of 36 person = 36 x 15 = 540 years
age of teacher = ( age of 36 person) - (age of 35 person)
= 540 - 490
= 50 years
