An Age-Old Question...

[Tricky]

When I am as old as my father is now, I shall be five times as old as my son is now. By then my son will be eight years older than I am now. The combined ages of my father and myself are 100 years. How old is my son? <img src=/S/smile.gif border=0 alt=smile width=15 height=15>
