QUES1. You wake up one morning and there's been a power outage. You know you have 12 black socks and 8 blue ones. How many socks do you need to pull out before you've got a match?:grab:


QUES2. involves the truthtellers and the liars. It goes like this: You're trying to get to Truthtown. You come to a fork in the road. One road leads to Truthtown (where everyone tells the truth), the other to Liartown (where everyone lies). At the fork is a man from one of those towns -- but which one? You get to ask him one question to discover the way. What's the question?:grab:

dude
I think the answer to the question about truthtown should be

"How can I reach ur place"
Both will point to Truthtown only

truthtown man will point to his town properly

man from false town also will point to his town wrongly which incidentally is the route to truthtown.

Dude..
Since u gotta pay him on 7 different days and u have only 3 different pieces(if u have 2 cuts made on the bar) only option is to get back and pay

Afterall u getback only what u gave him assuming that he din have any money but assuring that he gets paid everyday and
off course ASSUMING that HE DOESNT SPEND THE GOLD PIECE!!!!!!!!!!!!!!!!!!!1

I cun exactly understand it.
Provide more gyaan into it

Also plz explain how many squares can be formed in a chessboard

"How can I reach ur place"

Kartik C

The logic for subtracting 4*9C2 was that the outermost four boundary lines can never be diagonals of any polygon we can make from the 81 points.

Now each line has 9 points and no. of line segments from these 9 points are 9C2
so for 4 lines, total number of line segments are 4*9C2.

And for the number of squares in the chess board, they are 1+2^2 +3^2 +4^2 +...+8^2 =204
