Answer 1

9514 1404 393

Answer:

  32

Step-by-step explanation:

The average of a set of numbers is their total, divided by the number of them. That means their total is the product of the average and the number of numbers.

The total of ages for the 11-man squad is 11·22 = 242 years.

The total of ages for the 10 remaining players is 10·21 = 210 years.

The injured player contributed 242 -210 = 32 years to the total for the 11-man team.

The injured player was 32 years old.
