I have a question
for anyone who promises not to google the answer:

A pack of cards has 52 cards. You are in a dark room with this pack of cards. You have been told that inside the pack there are 42 cards facing down, 10 cards facing up.

You have been asked to reorganize this pack of cards into two decks – so that each deck contains an equal number of cards that are face up. Remember, you are in darkness and can’t see.

How will you do it?

Are the face up ones all together or scattered through?
because if they're all together you could just deal the pack into two decks.

Easy.
1. Turn light on
2. Throw cards in bin
3. Torture the twat who thought you'd do such a stupid, pointless excercise to death using techniques from the Japanese WWII canon.
4. Crack one off

He has two sons.
One is shit TV magician Martin - the other is a derelict alkie that an ex of mine met in a pub in Old Street. Bitter and fucked up, he hates his dad with a violent passion.

Great, eh?

He sounds OK to me.
I also hate his Dad with a passion.

Is it something along the lines of
deal them into 26 piles of 2,
turn over 12?? (the bit I'm still checking) of them
add 13 piles to one half, 13 to the other.

You're on the right track with turning over
but you're not constrained on how many face DOWN cards are in each pile, just face up...

Throw away 51 cards
Tear the last card in half. Done.
( Labia Majora You keep on talking but it makes no sense at all, Thu 23 Sep 2010, 13:50, Reply)

FFS that's simple then
just flip over 10 cards
