"With power comes responsibility" by Spider-man. The word 'Great' was removed to add twist. ๐Ÿ˜€

5. In order to ensure that one forecast is correct, how many different forecasts must be made of 5 football games?

Answer: 243 Forecasts.
We will have to consider each game separately, because each game may be won, lost or drawn by one of the teams. Therefore there are 3 possibilities in every game.
The first game has 3 possibilities and for each one of the possibilities the second game has 3 possibilities. Therefore there are 9 possible forecasts for the first 2 games.
For each of 9 forecasts of the second game, the third game has 3 possibilities, which makes it 27 forecasts and so on.
Therefore for 5 games there are 3 X 3 X 3 X 3 X 3 = 243 Possibilities.

B = 160 habitable floors in Burj Khalifa (Wikipedia Information under Technical Details)
C = 2007 : The elder Google Co Founder Larry Page married Lucinda Southworth at Richard Branson's Caribbean island, Necker Island in 2007.
D = 37 chapters in J.K. Rowlings "Harry Potter and the Goblet of Fire"
E = 1967 was the year when Infosys founder Narayana Murthy obtained his Bachelor's degree in Electrical Engineering.

So, A+B+C+D+E= 860+160+2007+37+1967 = 5031

9. Answer to this Question is here: #-Link-Snipped-##-Link-Snipped-#
Answer: Well, this was the real twister for all of you. If you followed that page, you'd see a big 'Open Source' logo. But at the bottom, it mentioned it wasn't that easy. If you looked at the title of the page (that is the top of your window), it said "Follow The Instructions".

The instruction was clear - "Open Source" and you had to open the source code of that page! Once you opened the source code, you had to scrawl down (we intentionally left lot of white space in there ๐Ÿ˜‰ ) and at the bottom, you'd see the answer -

"CE Rocks!"


We hope you enjoyed the Quiz ๐Ÿ˜
