Puzzle No: 255 July-21-2008(4) @ Novell

Yes, i know that, title looks weired and confusing. But while managing my backup i found this old puzzle with solution. Let me explain in detail. When i was in Novell, i used to wrote articles on SLES / SLED. Due to that interest, one day my friend redirected me to puzzle section of company wide circular, it was mostly for social activities. First top five, who solved that puzzle got their name in next circular. Imagine your name around 500+ people. So i thought let’s jump in this fame game

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!
