Difficult question

HAAAAAAAAAAAA! GREAT! I love it! THAT's the answer. It's gotta be!



And if you like the tricks with numbers, listen to this one. It's an ancient one. Originaly it was about camels, but since this is an FS forum, I'll
adapt it a bit. So it goes:

Once upon a time there was a man who was working hard all his life and at the eve of his life he had an airline company consisted of 17
planes. (We'll have to assume they were the same brand!)
But that was not all he had; he also had three sons: the oldest, not so old and the youngest.
As it sometimes happens, he felt he was parting with life, so he summoned his sons and at his death bed he told them:
"My dear sons, it's time for me to go where every living thing goes. I have acomplished many things, but what really matters is this
company. Don't reduce it; don't sell the planes once I'm gone. I leave it all to you and the way you will divide it amongst yourselves will be
this way:

The oldest one, you will inherit 1/2 of the planes!
Not so old one, you'll get 1/3 of the planes!
The youngest one will get 1/9 of the planes!

As he had said that, he passed away.

The brothers knew right away it will be impossible to fulfill the father's wish without selling a plane. And yet, they have promissed not to do
so. They also knew their father was not senile and he knew what he was talking about very well. They tryed everything, but in vain.
So they decided to call for help.
They knew there was a wise man in a distant country so they sent him a mail:
"We need your help urgently! We'll send you a plane to pick you up, just say when and where."
He promptly replyed:
"I accept the invitation. No need to send a plane for me - I'll come with my own. But you will pay me 100 000 $."

OK!

So to make a long story short, he came, solved the problem, took the money and flew back home.

How did he do that!?

(Dan, maybe we should have psted this as an easter egg question!? )



P.S. The answer is VERY ELEGANT!!!
