You Are Blindfolded And Sit In Front Of A Table. On The Table Are Many Coins, 10 Of Which Have Heads Facing Up. How Do You Split The Group Of Coins Into Two Groups Such That The Same Number Of Coins Are Heads-up In Each Group?

Answer»

You don’t know how many coins there are and you can’t tell which side is facing up in any way.

LET’s say there are 50 coins and we SEPARATE 10 of them. Now we have a GROUP of 10 and a group of 40.

Let’s assume there are 3 HEADS in the group of 10. Then there will be 7 heads in the group of 40.

Group

Now we TURN over all the coins in the group of 10.

Group1

That’s it! 7 heads in each group!
