    Answer : Option A

    Explanation :

    Total age of the committee = 10 ∗ 40 = 400 years

    Age of retired member = 52 years

    Age of new member = 38 years

    As per question, we will minus 52 years and add 38 years in the total age then divide by 10 to find the new average age of the committee.

    = = = = 38.6 years
