You are lost in the woods and the path you are following forks into two: a path to the left and one to the right. One path will lead you to safety while the other will cause you to be lost forever.
At the fork are two twin sisters who know which path is which. The sisters are identical in every way except one: one of the sisters always tells the truth while the other always lies.
You can ask only one question and you don’t know which sister is which. What can you say to them so you know which path to take?
Ask one of the sisters which path their sister would tell you to take.
Let’s say the left hand path is the correct one to follow. The sister that lies knows their truthful sister would tell you the left hand path, so as they always lie they will tell you the right hand path.
The honest sister knows their lying sister will tell you the right hand path and because they’re honest, they will tell you this. So you should follow the opposite path to that which you are told, regardless of which sister tells you.

You're on a ski lift, going from the bottom of the mountain to the top. How many chairs from the other side will you pass by?
A few choices:
1. Half of them
2. 2/3 of them
3. All of them (but yours)
4. 3/4 of them
(The 'Google Riddles' are interview questions those who wish to get hired were asked).
The answer is C - all of them but yours.
The chairs are in a giant loop, with several stopping places on the way to the top, and you will see all the chairs probably more than once before you get up there.
If you pile up coins one on top of another until they get as high as the Empire State Building - would you be able to fit them all into one average sized room?
(The 'Google Riddles' are interview questions those who wish to get hired were asked).
Yes, you could.
How do we know this? If the Empire State Building is about 100 levels tall, and each level is about an average room in height, that means we can divide the giant pile into 100 piles of one level each. Would 100 piles of coins fit in a room? Of course it will, with lots of room for more.
You're a pirate captain and your crew is about to divvy up the gold you've plundered. They are waiting for your wisdom on the subject.
However, if less than half the pirate crew agree with your division of the gold, they will make you "walk the plank".
How would you divvy up the gold in a way that will keep you alive and with your pockets full of gold?
(The 'Google Riddles' are interview questions those who wish to get hired were asked).
Share the gold with only 51% of the pirates. The other 49% will want to kill you but who cares - they're the minority! This way you'll get the max amount of gold with the majority of pirates voting to keep you alive.
You're sitting in a car. The car has helium balloons tied to its floor. The windows in the car are closed and locked and the Air conditioner isn't working.
What will happen to the balloons when you press on the gas?
Will they move forward, stay in place, move backwards...?
The answer is they will move forwards.
Because helium is lighter than air, it will go where air isn't. When the car is pushed forward the air moves backwards, so the helium balloons will move to where the air is not - forward.
You have 3 boxes. One of them contains a prize. You were allowed to pick just one of them.
You pick - and it's empty.
With 2 boxes left, you now have one box in your hand and another box in front of you. If given the chance to exchange your box with the box in front of you, would you do it? Why, and why not?
(The 'Google Riddles' are interview questions those who wish to get hired were asked).
In the beginning, with 3 boxes, things were simple. You had a chance of 1 in 3 to find the prize. NOW we know that one of the boxes is empty but you still made a guess of 1 in 3, now you have a new choice of 1 in 2. Your probability goes up and that is why you SHOULD CHANGE THE BOX.
Don't feel bad if you disagree, this riddle has been hotly debated.
