The average age of eight teachers in a school is 40 years. A teacher among them died at the age of 55 years whereas another teacher whose age was 39 years joins them. The average age of the teachers in the school now is (in years)
Average age of 8 teachers = 40 years
=> Total age of teachers = $$40 \times 8=320$$ years
A teacher at the age of 55 years died and a teacher aged 39 joined them
=> New total age = $$320 - 55 + 39=304$$
$$\therefore$$ Required average = $$\frac{304}{8}=38$$ years
=> Ans - (C)
