So, title contains Puzzle Number of that puzzle which i attended very first time.

What would be the value of X and Y to correct  X * Y * XY = YYY equation?

I was BASH freak, due to my Q/A Automation work @ Novell. So i thought, let’s not find one result, make it automated to find different possibilities of X and Y.  I decided to wrote BASH script with TRY / ERROR methodology.   Which took my 30 Minutes due to cosmetic changes. I was feeling top of the world because of my Hard Work + Smart Work deadly combo . I submitted my solution (Answer + Script). But, in next circular i was not in top five .

Then i did retrospective analysis of my failure, which helped me to manage  my name in top five for next few month. I also took part in Novell Test Fest 2008 by winning series of on-line quizzes. My team was  First Prize Winner in Novell Test Fest 2008. Then my friend, who had redirected me to that Puzzle Fame Game (For me at-least) came and told me that you are true winner, you have not used Google. I didn’t say anything, i just smiled

Answer of the puzzle and positive output from script with statistics:

Try & Error Count :  57

Possibility of X  :  3

Possibiligy of Y  :  7

So, YYY Would be  :  777

So, XY  Would be  :  37

So, X * Y * XY    :  777

Comparing Eqation X * Y * XY = YYY

RESULT = POSITIVE

So, Possibility of X = 3 and Y = 7 to make the equation X * Y * XY = YYY Possible!
