Tokarev S.I.

On February 16, 2003, a boy said: "The difference between the number of full months and full years I have lived is now 111 for the first time." When was he born?
Let the boy have lived $x$ years and $y$ months. Then $12 x+y-x=111$, that is, $11(10-x)+1=y$. Since $y<$ 12 , then $x=10$ and $y=1$.

## Answer

January 16, 1993.
