V-Riddle: Superbly Tough Riddle

I came across this picture somewhere in the Net few weeks back.

Along the picture, there was a manuscript which turned out to be a riddle.
It is superbly tough... Well, it is known as the Einstein Riddle after all...

From that site, it claims that whoever manage to solve the riddle will win a GOLD BAR!

*THE ADVENTURE OF THE NATIONAL TREASURE CONTINUES*

I have attempted the riddle and it took me few days-to-weeks to get the answer!?

*That explains why I was Missing In Action for a couple of weeks*
(yeah, great excuse~ LOL)

So, don't bother trying...The GOLD BAR is already MINE!! *laughs hysterically*
*I wish ;p*

Anyways, enjoy attempting the riddle if you have the time...
