You find yourself in a strange place guarded by two guards.One of the guard always say truth while other always lies.You don\’t know the identity of the two.You can ask only one question to go out from there. What should you ask?

What belongs to you but others use it more than you do?

Suppose you\’re on a game show, and you\’re given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1 [but the door is not opened], and the host, who knows what\’s behind the doors, opens another door, say No. 3, which has a goat. He then says to you, \”Do you want to pick door No. 2?\”

Is it to your advantage to switch your choice?

Pirate Peter had been captured by a Spanish general and sentenced to death by his 50-man firing squad.

Peter cringed, as he knew their reputation for being the worst firing squad in the Spanish military. They were such bad shots that they would often all miss their targets and simply maim their victims, leaving them to bleed to death, as the general’s tradition was to only allow one shot per man to save on ammunition. The thought of a slow painful death made Peter beg for mercy.

“Very well, I have some compassion. You may choose where the men stand when they shoot you and I will add 50 extra men to the squad to ensure someone will at least hit you. Perhaps if they stand closer they will kill you quicker, if you’re lucky,” snickered the general. “Oh, and just so you don’t get any funny ideas, they can’t stand more than 20 ft away, they must be facing you, and you must remain tied to the post in the middle of the yard. And to show I’m not totally heartless, if you aren\’t dead by sundown I’ll release you so you can die peacefully outside the compound.

I must go now but will return tomorrow and see to it that you are buried in a nice spot, though with 100 men, I doubt there will be much left of you to bury.”

After giving his instructions the general left. Upon his return the next day, he found that Peter had been set free alive and well. “How could this be?” demanded the general. “It was where Peter had us stand,” explained the captain of the squad.

Where did Peter tell them to stand?

Two men working at a construction site were up for a challenge, and they were pretty mad at each other. Finally, at lunch break, they confronted one another. One man, obviously stronger, said “See that wheelbarrow? I’m willin’ to bet $100 (that’s all I have in my wallet here) that anything you can wheel to that cone and back, I can wheel twice as far. Do we have a bet?”

The other man, too dignified to decline, shook his hand, but he had a plan formulating. He looked at the objects lying around: a pile of 400 bricks, a steel beam, the 10 men that had gathered around to watch, and a stack of ten bags of concrete mix; he thought for a while, and then finalized his plan.

“All right,” he said, and revealed his object.

That night, the strong man went home thoroughly teased and $100 poorer.

What was the weaker man’s object?
