Golu has 100 identical coins (with head side and tail side) which he wants to donate to someone. There are many people who are aiming to get this collection of 100 coins. So Golu created a puzzle using all 100 coins and declared that the one who will solve his puzzle will get all the coins. You desperately need money so solving the puzzle is only option you have.

The Problem goes like this:

All 100 coins are laying flat on a table. 80 of them are heads up and remaining 20 are tails up. You can’t feel, see or in any other way find out which side is up. Split the coins into two piles(sets) such that there are the same number of tails in each pile.

[Baby Hint]: If number of coins in first pile is n then other pile will have 100-n coins.
