ws increased by 2 years. How old is the new teacher?
​

Answer 1

Answer:

51

Step-by-step explanation:

There are 8 teachers.

Let the total age be A.

Then avg age = A/8.

the average age was increased by 2 years means whosoever has come is of greater age than who has left.

New average = A/8 + 2

Increment in total age = 8 x 2 = 16.

New teacher's age = 35 + 16 = 51.
