Step 2: Count how many times each age appears.
Step 3: For age 22, it appears 2 times.
Step 4: For age 23, it appears 1 time.
Step 5: For age 24, it appears 3 times.
Step 6: For age 25, it appears 1 time.
Step 7: For age 26, it appears 1 time.
Step 8: For age 27, it appears 2 times.
Step 9: For age 28, it appears 1 time.
Step 10: For age 29, it appears 1 time.
Step 11: For age 30, it appears 3 times.
Step 12: Compare the counts of all ages to find the highest count.
