Either stupid or abnormally gifted

Can you solve the puzzle of the petals round the rose? You may get it very quickly and wonder what the fuss is about, or take several hours (like Bill Gates) to work out what's going on.

I can't tell you the solution, though I do know it. All I can tell you is the name may be significant and every answer is either even or zero. Some say that the more intelligent you are, the quicker you solve it. I got it in under a minute, so they're clearly wrong.
