in fact, I had the answer in a few seconds and left me wondering how this was even considered a 'brain teaser'. Maybe the analyst training over here is making a difference.
I too saw it was obviously an even number in order for then to pair up.
since pairing them up halves thier numbers and when they are halfed they are one les than the posts and when they are not they are one more, one plus one is two, which is the half of the seagul numbers, so they number four, and the posts 3.
now for a less numberically intenive brain teaser: Two girl walk into a room, they have the same birthday, (that is, year month and day is the same) and they have the same mother. A man asks them "Are you twins?" they reply "no". So, what the heck is going on here? how can this be?
