Answer:
age of principal = 39
Step-by-step explanation:
24 students + 1 principal / 25 = 15
24 students + 1 principal = 15 × 25
24 students + 1 principal = 375
If principal is excluded
24 students / 24 = 14
24 students = 14 × 24
24 students = 336
• age of principal = total - students
= 375 - 336
= 39
