9. Xiao Ming said: "My mom is 24 years older than me, and two years ago, my mom's age was 4 times mine." How old is Xiao Ming this year?
【Analysis】10 years old
Exam Point: Age problem;
Since the age difference between 2 people remains constant, 2 years ago, the mother was also 24 years older than Xiaoming;
Therefore, Xiaoming's age 2 years ago was: $24 \div (4-1) = 8$ years old;
So Xiaoming's current age is: $8 + 2 = 10$ years old.
