You have 12 black socks and 12 white socks mixed up in a drawer. You’re up very early and it’s too dark to tell them apart. What’s the smallest number of socks you need to take out (blindly) to be sure of having a matching pair?

Show the answer »

Three socks. If the first sock is black, the second one could be black, in which case you have a matching pair. If the second sock is white, the third sock will be either black and match the first sock, or white and match the second sock.

Oct 31 = Dec 25

How can Oct 31 and Dec 25 be the same?

Because Oct 31 represents the octal (base 8) number 31, which, when converted to decimal, is 25. Dec 25 is short for Decimal 25, thus the two are equal.

Up and Down and Round About

I’m up and down and round about,
yet all the world can’t find me out.
Though thousands have employed their leisure,
they never yet could find my measure.
I’m found in almost every garden,
In a compass or a farden.
There’s neither chariot coach nor mill
may move one inch except I will.

What am I?

Show the answer »

A circle.
