The captain of a cricket team of 11 members is 26 years old and the wicket keeper is 3 years older. If the ages of these two are excluded, the average age of the remaining players is one year less than the average age of the whole team. What is the average age of the team?
Answer: Option
Explanation:
Let the average age of the whole team by x years.
11x - (26 + 29) = 9(x -1)
11x - 9x = 46
2x = 46
x = 23.
So, average age of the team is 23 years.

Age of the captain of 11 members is 26 and the age of the wicket keeper is 4 year so how 26+29? Please anyone explain me.

Let the average age of 9 members be x.
(x+55)/11 - x/9 = 1
=> x=198.
(198+55)/11 => 23.
(x+55)/11 - x/9 = 1
=> x=198.
(198+55)/11 => 23.

In question its given 3 years older. It should be clearly given like 3 years older than captain.

"11x - (26 + 29) = 9x - 9" how this 9x - 9 came from? please explain. I don't understand.

Cross check the answers:
X = 253/11 = 23,
X = 253 - 26 - 29 = 198,
198/9 = 22.
X = 253/11 = 23,
X = 253 - 26 - 29 = 198,
198/9 = 22.

To be simple;
Avg - 55 = avg-1( bcoz if excluded 1 yr less than avg),
Avg = 23.
Avg - 55 = avg-1( bcoz if excluded 1 yr less than avg),
Avg = 23.

One year less than average then why are you using 9x+1? you can use 9x-1 na ?

How 29 came because 26 years old is captain and 3 years old is wicket-keeper.
