Gold Coin

Two men find an old gold coin and want to have a coin toss with it to decide who gets to keep it. The only problem is the coin is heavier on one side so it comes up heads more than tails.

What is a fair way for the men to toss the coin and decide who gets to keep it?

View Answer
They toss the coin twice.  Each man picks heads or tails on the first coin toss and on the second coin toss they switch.  So if you picked heads on the first coin toss you would have tails for the second coin toss.  In this way no one has an advantage over the other.

Honest Politicians

There is a room full of 100 politicians. Each one is either honest or a liar. You know to facts about these politicians:

1. At least one of them is honest.
2. If you pick any two politicians, at least one of them is a liar.

From this information, can you determine how many politicians are honest and how many are liars?

View Answer
One politician is honest and 99 are liars.  We know from the facts at least one politician is honest.  If more than one were honest you could potentially pick two politicians that would both be honest.  However, fact number two tells us that at least one of the politicians would have to be a liar.

Matters that Count

Placed above, I make greater things small. Placed beside I make small things great. In matters that count, I always come first. Where others increase I keep them the same.

What am I?

The number 1. If you put the number one above another number it turns it into a fraction.  If you put it next to another number it makes the number larger.  If you put things in order the number one comes first.  If you multiply by one the number stays the same.

River Crossing

You have a fox, a chicken and a sack of grain. You must cross a river with only one of them at a time.

If you leave the fox with the chicken he will eat it; if you leave the chicken with the grain he will eat it.

How can you get all three across safely?

View Answer
Take the chicken over first. Go back and bring the grain next, but instead of leaving the chicken with the grain, come back with the chicken. Leave the chicken on the first side and take the fox with you. Leave it on the other side with the grain. Finally, go back over and get the chicken and bring it over.
