Number of members in the team = 11 Let the average age of the team = x ⇒ (Sum ofthe ages of all the 11 members of the team) /(11) = x ⇒ Sum of the ages of all the 11 members of the team = 11x Age of the captain = 26 Age of the wicket keeper = 26 + 3 = 29 Sum of the ages of 9 members of the team excluding captain and wicket keeper = 11 x - 26 - 29 = 11x - 55 Average age of 9 members of the team excluding captain and wicket keeper = (11x - 55)/9 Given that (11x - 55 /9 = (x - 1) ⇒ 11x - 55 = 9 (x - 1) ⇒ x = 46/2 = 23 years
