Answer 1

Step-by-step explanation:

A school has 8 teachers in a school. A 35-year-old teacher went to the place maari and another teacher came instead, the average age of the teachers was increased 2 . How old is the new teacher?

• Let the average age of the teacher be t1
• Let the age of teacher who joined be t2
• So the total age of 8 teachers was 8t1
• Now the sum of ages after the new teacher joined will be 8t1 – 35 + t2
• According to the question average of this was increased by 2
• So 8t1 – 35 + t2 / 8 = t1 + 2
• So 8t1 – 35 + t2 = 8t1 + 16
• So – 35 + t1 = 16
• So t1 = 16 + 35
• Or t1 = 51
• Therefore the age of new teacher who joined the school is 51 yrs.
