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.

Let whole team average age= (55+9x)/11 ...eq (1)
Average age of 9 member =9x/9= x,
Difference between average =1.
Lets;
((55+9x)/11)-x = 1,
x=22,
Then put x value into eq (1).
We get average value =23.
Average age of 9 member =9x/9= x,
Difference between average =1.
Lets;
((55+9x)/11)-x = 1,
x=22,
Then put x value into eq (1).
We get average value =23.

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.

(X/11) = Y.
X = 11Y,
26 + 29 = 55,
(X-55)/9 = (Y-1)9,
Y = 23.
X = 11Y,
26 + 29 = 55,
(X-55)/9 = (Y-1)9,
Y = 23.

Let Avg. Age Of team = X.
Capt. + wicket keeper's age = 26+( 26+3)= 55.
According to ques;
11x - 55 = 9(x-1),
=>11x - 55 = 9x - 9,
=> 11x - 9x = 55 - 9,
=> 2x = 46.
=> X = 46/2 = 23 yr.
Capt. + wicket keeper's age = 26+( 26+3)= 55.
According to ques;
11x - 55 = 9(x-1),
=>11x - 55 = 9x - 9,
=> 11x - 9x = 55 - 9,
=> 2x = 46.
=> X = 46/2 = 23 yr.

@Habiba
Please explain the Term 11x-(26+(26+3)=9 (x-1).

let's, average age = x.
According to the math concept,
Totall team member (11)* average age - (captain +wicket kepper) age= rest of 9 members* (average age -1).
11x-{26+(26+3)} = 9(x-1),
11x-55 = 9x-9,
11x-9x = 55-9,
2x = 46,
x = 23.
According to the math concept,
Totall team member (11)* average age - (captain +wicket kepper) age= rest of 9 members* (average age -1).
11x-{26+(26+3)} = 9(x-1),
11x-55 = 9x-9,
11x-9x = 55-9,
2x = 46,
x = 23.

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.

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.
