Problem Analysis

We are given that the average age of the players in a football team is 22 years. During a match, one player was sent off the field, and as a result, the average age of the remaining players decreased to 21 years. We need to determine the age of the player who was sent off.

Solution

Let's assume there are n players in the team. The sum of their ages before the player was sent off would be n * 22, and the sum of their ages after the player was sent off would be (n - 1) * 21.

We can set up the following equation to solve for n:

n * 22 - x = (n - 1) * 21

Where x is the age of the player who was sent off.

Simplifying the equation, we get:

22n - x = 21n - 21

Rearranging the equation, we get:

x = 22n - 21n + 21

Simplifying further, we get:

x = n + 21

Therefore, the age of the player who was sent off is equal to n + 21.

To find the value of n, we need more information. Unfortunately, the given information is not sufficient to determine the age of the player who was sent off.

Conclusion: The age of the player who was sent off cannot be determined with the given information.
