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.

26 is age of captain.
And we are given that wicket keeper is 3 year older than captain so age of wicket keeper is 29 (26+3).
And we are given that wicket keeper is 3 year older than captain so age of wicket keeper is 29 (26+3).

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.

(x-26-29)/9) -1= x/11.
Why is this equation not right? Anyone, please explain to me.

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.
