Question 1: Xiao Ming is two years older than Xiao Li. Four years later, their age is 16. How old is Xiao Ming this year?

Let Xiao Li be x years old, and Xiao Ming be x + 2 years old
X+2+4+X+4=16
X=3
So Xiao Ming is 5 years old

Six years ago, my cousin's age was three times that of Xiaoming. Now my cousin's age is two times that of Xiaoming. Xiaoming's age this year is three times that of Xiaoming______ ．

Suppose Xiaoming is x years old, then his cousin is 2x years old. Six years ago, his younger brother was X-6 years old, and his cousin was 2x-6 years old. According to the meaning of the question, we can get: 3 (X-6) = (2x-6), and the solution is: x = 12. A: Xiaoming is 12 years old this year. So the answer is: 12
