Thread: Coins on the table

Problem Statement:

There is a table on which a number of coins are placed. You also know that there are as many coins with Head up as many coins with Tail up. Now you have to divide the coins (number of coins is even) into two equal piles such that number of coins with Heads up and Tails up in either piles be the same. The catch is you are blind folded and you cannot determine the sides (for sure) if you are blinded.

Solution:

Divide the coins in half by quantity (easy to count coins while blindfolded)

Then, flip all the coins in one pile over.
