A Bottle and a Cork

A bottle and cork cost $1.10. If the bottle costs a dollar more than the cork, how much does the cork cost?

Most people guess 10 cents, but $1 more than 10 cents is $1.10, which would mean the total cost would be $1.20, not $1.10.

The correct answer is 5 cents. If the cork costs 5 cents, then the bottle costs a dollar more, or $1.05, making the total cost $1.10.

The Average of Three

There are three numbers. The first two are 2/3 and 3/4.

What does the third number have to be to make the average of all three be 2?

4 7/12

In order for the average of three numbers to be 2, they must all add up to 6. That gives you this equation:
2/3 + 3/4 + n = 6

Solve for n = 55/12, or 4 7/12.

How to Make the Great Escape

Shawn and Kyle are bunk mates in prison and are desperate to escape. There is an unbarred window high above them, but the walls are smooth and it’s too high for them to reach even when standing on each other’s shoulders. Their cell has no furnishings other than a toilet and even when standing on the toilet and each other’s shoulders, they can’t reach the window.

They’ve tried digging through the dirt floor but the wall extends 50 feet below. How could escape through the window?

Smurf imprisoned

They could dig down with their hands, but it would take too long to dig 50 feet down. Instead, they could pile the dirt they dig up to give them enough height to reach the window. If they put the toilet seat down, they could pile the dirt on top, then get on each other’s shoulders to reach the window. That would mean only one of them would be able to get out. The remaining prisoner could either continue piling dirt to account for the missing guy or the escaped prisoner could come back with a rope to help his mate escape.

How Old Is The Shepherd?

There are 125 sheep and 5 dogs in a flock.

How old is the shepherd?

You can’t determine the answer.

I debated adding this riddle because it is less of a riddle and more of an illustration of how kids are (or are not) being taught to think for themselves. But after reading how kids feel the need to make up an answer without understanding why, I thought this could be a good reminder for all of us to exercise our critical thinking skills.
