Now there are two piles, one with 15 cards and one with 37 cards and both of them will obviously have the same number of inverted cards.<br /><br />If you want to understand mathematically, let us say that there were x inverted cards in the top 15 cards of the deck. Then the remaining 37 cards will comprise of 15-x number of inverted cards.<br /><br />If we reverse the 15 cards the number of inverted cards will become 15-x and the number of inverted cards will be same in both the pilesGenius Logic Puzzleshttp://gpuzzles.com/brain-questions/logic-puzzles-and-riddles/noreply@blogger.com
