Q.
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.

Many thanks to A.N.V.K.Chaitanya for the answer !
You first split the coins up into two equal piles. Then the number of heads in one pile is equal to the number of tails in the other and vice versa.
Then the next step is to turn every coin in one of the piles around. Then you’ll have the same amount of heads/tails in each pile.
what means of piles?
