Puzzle #70: Equal Heads (Outstanding Puzzle!)

This one is one of the best puzzles I have come across in recent times…contributed by Vardhan Rajkumar based out of London. I do not know the original source of the puzzle. No special knowledge or skill required, so suitable for all ages.

You have 100 coins.  10 of them are head up and 90 tails up. You have been blindfolded. You need to divide the coins into 2 groups that have the same number of heads.

As always, please send your answers directly to me at alokgoyal_2001@yahoo.com. If you like the puzzle, please share it with others. If you have interesting puzzles to share, please send them to me at my e-mail given above.

 

Enjoy applying the heads 🙂

    Hi Alok,

    I would make two piles. 10 coins and 90 coins and then flip all the coins in the 10 stack. That should do it.

    This one was fun!

    Cheers,

    Mihir
