Cong Cong said: I am eight years old and my mother is five times my age. A few years later, my mother was five times as old as Congcong.
Cong Cong is 8 years old and her mother is 5*8=40 years old.

Suppose my mother is three times as old as Congcong after X years, and get the equation:

40+x=3(8+x)

40+x=24+3x

16=2x

x=8

So eight years later, my mother is three times as old as Congcong.
