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.

Avg of full team x = (9x9+26+3)/11.
Avg of 9 players x9 = x-1.
x = (9(x-1)+29)/11.
11x = 9x-9+29.
2x = 20.
x = 10.
Average age of whole team is 10 years.
Avg of 9 players x9 = x-1.
x = (9(x-1)+29)/11.
11x = 9x-9+29.
2x = 20.
x = 10.
Average age of whole team is 10 years.

wicket keeper is 3yrs older than captain.
so we get age of wicket keeper as 26+3=29 yrs.

Total ageaof of 11 player ages 26 = 26 * 11 = 286.
Total of 11 player whose age 29 = 29 * 11 = 319 Difference = 33 average 1 less,
33 - 10 = 23.
Total of 11 player whose age 29 = 29 * 11 = 319 Difference = 33 average 1 less,
33 - 10 = 23.

11 MEMBERS TEAM PLAYERS AGE OF 26 YEAR OK
1 (ONE) MEMBER IS WICKET KEEPER 3YEARS OLDER THEN REAMING PLAYERS
11-1=10 1 IS WICKET KEEPER
26-3=23
1 (ONE) MEMBER IS WICKET KEEPER 3YEARS OLDER THEN REAMING PLAYERS
11-1=10 1 IS WICKET KEEPER
26-3=23

Here the average of 11 members = x.
If two are excluded then average of 9 members is 1 year less than the average of the whole team so = 9(x-1).
If two are excluded then average of 9 members is 1 year less than the average of the whole team so = 9(x-1).

Let the Avg. Age = X.
=> 11x-(26+29) = 9(x-1).
=> 11x-55 = 9x-9.
=> 11x-9x = 55-9.
=> 2x = 46.
=> x = 46/2 = 23yrs. answer.
=> 11x-(26+29) = 9(x-1).
=> 11x-55 = 9x-9.
=> 11x-9x = 55-9.
=> 2x = 46.
=> x = 46/2 = 23yrs. answer.

Is any body tell me that why we are reducing 1 from average age of 9 persons (x/9-1) ?
In above equation why we reducing that one?

The age of captain is 26 and wc age is more than 3.
So 29,
26 + 29 = 55,
55 - 9(team average is less one ) = 46,
And 46/2 = 23.
So 29,
26 + 29 = 55,
55 - 9(team average is less one ) = 46,
And 46/2 = 23.

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).
