Question: Zhi Wei was born on christmas day in 1983. His father shares the same birthday, but he was born in 1951. In which year will Zhi Wei's age be exactly 1/3 of his father's age?

 


Hi Clement.

When Zhi Wei is one-third of his father's age, then the other two-thirds of his fathers age are the years when his father was living and Zhi Wei was not. So if you can figure out how many years old his father was when Zhi Wei was born, you just need another half of that to know the answer to your question.
