Given:

The captain's age = 26 years

The wicket keeper's age = 26 + 3 = 29 years

The cricket team has 11 members.

Calculation:

Let the average age of the whole team be A years.

The total age of the team = 11A

The total age of the remaining 9 players = 11A - (26 + 29)

Average age of the remaining 9 players = (11A - 55) / 9

Given that the average age of the remaining players is one year less than the average age of the whole team, we have:

A - 1 = (11A - 55) / 9

⇒ 9(A - 1) = 11A - 55

⇒ 9A - 9 = 11A - 55

⇒ 55 - 9 = 11A - 9A

⇒ 46 = 2A

⇒ A = 23

The average age of the team is 23 years.
