A Correct answer
Explanation

The total age of 11 players is 11 * 22 = 242. Including the coach, there are 12 people with an average age of 23, so the new total is 12 * 23 = 276. The coach's age is 276 - 242 = 34.

AI explanation

The total age of the 11 players is 11 multiplied by 22, which equals 242 years. When the coach is included, there are 12 people with a new average age of 23, making the new total age 12 multiplied by 23, which equals 276. The age of the coach is the difference between these two totals: 276 minus 242 equals 34 years.
