By | August 11, 2017

Problem: Suppose that, you are blindfolded and 10 coins are place in front of you on table.
Now, you are allowed to touch the coins, but you canβt tell which way up they are by feel.It is told that there are 5 coins head up, and 5 coins tails up but not which ones are which. And, obviously you have to believe, since you are blindfolded and are playing game with your wish. π
So, How do you make two piles of coins each with the same number of heads up? You can flip the coins any number of times.

This seems to be a very difficult puzzle, but its really not.
Please take your time before jumping on the solution directly.

Solution:

Make 2 piles with equal number of coins. Now, flip all the coins in one of the pile. And, BINGO. You have got same number of Heads Up in each pile. π

How this will work? lets take an example.

So initially there are 5 heads, so suppose you divide it in 2 piles.

Case:

P1 : H H H T T
P2 : H H T T T

Now when P1 will be flipped
P1 : T T T H H
