The Card Trick Riddle
A couple had to take shelter in a hotel for they could not proceed their journey in the rain. Having nothing to do at all, they started playing cards. Suddenly there was a short circuit and the lights went off. The husband inverted the position of 15 cards in the deck (52 cards normal deck) and shuffled the deck.
Now he asked his wife to divide the deck into two different piles which may not be equal but both of them should have equal number of cards facing up. There was no source of light in the room and the wife was unable to see the cards.
For a certain amount of time, she thought and then divided the cards in two piles. To the husbands astonishment, both of the piles had equal number of cards facing up.
How did she do it?

For a certain amount of time, she thought and then divided the cards in two piles. To the husbands astonishment, both of the piles had equal number of cards facing up.
How did she do it?
Hint:
The answer is very simple. All she had to do is take the fifteen cards from the top and reverse them. This would make another pile out of that and there will be two piles - one of 15 cards and one of 37 cards. Also both of them will have the same number of inverted cards.
Just think about it and if the mathematical explanation will help you understand better, here it is.
Assume that there were p inverted cards initially in the top 15 cards. Then the remaining 37 cards will hold 15-p inverted cards.
Now when she reverses the 15 cards on the top, the number of inverted cards will become 15-p and thus the number of inverted cards in both of the piles will become same. Did you answer this riddle correctly?
YES NO

The Graveyard Of Ol' Man Jenkins
There was a girl who was extremely brave and always bragged about how brave she was. Many of her classmates got sick and tired of her boasting, so they decided to play a trick on her. One day, a group of boys and girls walked up to her and said, " If you're so brave, we all dare you to go to the old graveyard at the back of Ol' Man Jenkins mansion all alone at midnight. Stand in front of a tombstone, rumor has it that if you do, a bony hand will reach out and grab you, dragging you underground! You said you were brave so that shouldn't be so hard! To prove that you actually went, stick a knife in front of a tombstone so in the morning, we'll know you were there." Of course, the girl couldn't refuse and agreed to the dare. At midnight, she did just as her classmates asked and went to the graveyard with a pocketknife. The night was cold and windy, blowing her dress, chills went up her spine. She slowly walked up to a tombstone and quickly stuck the pocket knife into the ground. She was beginning to feel not as brave as she thought she was. Turning around as fast as she could, she just wanted to get out of there right away! But, there was a problem. Something was stopping her from moving. Was it a bony hand trying to drag her down? A shrill scream was heard. The next morning, the boys and girls went to the graveyard to see if the girl had been there. To their horror, she was there, dead.
1) What prevented the girl from escaping the graveyard?
2) How did the girl die?
1) What prevented the girl from escaping the graveyard?
2) How did the girl die?
Hint:
1) The girl was wearing a dress at the graveyard. It was dark, so she hadn't noticed where she stuck the knife in the ground. She accidently stuck it in her dress (and the girl DID NOT get hurt by the knife in any way). That is what prevented her from running away.
2) Since the knife had her stuck, she was frighted that the rumor of the bony hand was true and had grabbed her, trying to pull her into the ground. She was truly terrified and died of fright. Did you answer this riddle correctly?
YES NO

100 Blank Cards Riddle
Someone offers you the following deal:
There is a deck of 100 initially blank cards. The dealer is allowed to write ANY positive integer, one per card, leaving none blank. You are then asked to turn over as many cards as you wish. If the last card you turn over is the highest in the deck, you win; otherwise, you lose.
Winning grants you $50, and losing costs you only the $10 you paid to play.
Would you accept this challenge?

Would you accept this challenge?
Hint: Perhaps thinking in terms of one deck is the wrong approach.
Yes!
A sample strategy:
Divide the deck in half and turn over all lower 50 cards, setting aside the highest number you find. Then turn over the other 50 cards, one by one, until you reach a number that is higher than the card you set aside: this is your chosen "high card."
Now, there is a 50% chance that the highest card is contained in the top 50 cards (it is or it isn't), and a 50% chance that the second-highest card is contained in the lower 50. Combining the probabilities, you have a 25% chance of constructing the above situation (in which you win every time).
This means that you'll lose three out of four games, but for every four games played, you pay $40 while you win one game and $50. Your net profit every four games is $10.
Obviously, you have to have at least $40 to start in order to apply this strategy effectively. Did you answer this riddle correctly?
YES NO
