Answer 2

Step-by-step explanation:

Given : -

• There are 8 teachers in a school.

• a 35 year old teacher was transferred and another teacher joined.

• the average age was increased by 2 years.

To Find : -

• How old is the new teacher?

Solution : -

• Let the total age be x

• Then avg age = x/8.

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

➻ New average = x /8 + 2

➻ Increment in total age

➻ 8 x 2

➻ 16

New teacher's age

➻ 35 + 16

➻ 51
