I thought it would be "cool" to have a thread for logic puzzles.

So here's one which I managed to solve (at least I think so) :P



Which one is the odd one out?

(Also six year-olds in Hong Kong are expected to be able to answer this :ohmy:)

My answer:

I made myself a little spreadsheet to figure it out and got the same answer as you.

Hopefully it's the right answer :P

It won't let me have a blank signature ...

This is one that went viral a month or two ago. Needless to say I didn't get it - not even close! How will you get on?

Albert and Bernard just become friends with Cheryl, and they want to know when her birthday is.
Cheryl gives them a list of possible dates:
May 15 May 16 May 19
June 17 June 18
July 14 July 16
August 14 August 15 August 17

Cheryl then tells Albert and Bernard separately the month and the day of her birthday respectively.

Albert: I don't know when Cheryl's birthday is, but I know that Bernard does not know too.

Bernard: At first I don't know when Cheryl's birthday is, but I know now.

Albert: Then I also know when Cheryl's birthday is.

So when is Cheryl's birthday?

Third from the left the only circle?

Fourth from the left different center?

Five from the left the smallest?

Are there several possible answers depending on ones own perceptions?

Gods I wish I could make up my mind.

Good thing I didn't grow up in Hong Kong! I'd be screwed for life.

If they are all odd then the most odd one would be more like another one?

My brain hurts. :S
