Blindfolded Coin Toss

Solution

We can solve this by splitting the coins into an equal number of sets. Now, we will flip the coins of one pile. 

For example:

Pile 1: THTTT

Pile 2: HHHHT

Now when we flip Pile 1 coins, 

Pile 1: HTHHH

Pile 2: HHHHT

There is an equal number of heads in both piles.
