So here I am back again with a collection of interesting brainteasers that are surely going to stretch your brain to think out of the box.

1. The Biggest Area

A farmer challenges an engineer, a physicist, and a mathematician to fence off the largest amount of area using the least amount of fence.
The engineer made his fence in a circle and said it was the most efficient.
The physicist made a long line and said that the length was infinite. Then he said that fencing half of the Earth was the best.
The mathematician laughed at the others and with his design, beat the others. What did he do?

2. Shot and Hung

A woman shoots her husband. Then she holds him under water for over 5 minutes. Finally, she hangs him. But 5 minutes later they both go out together and enjoy a wonderful dinner together. How can this be?

3. Two Deaths

Bob and Mary were found dead. The Inspector went to the house an wrote this in his journal:
-There was glass all around the bodies
-There were water stains in the carpet around them
-There was a table next to them
-The Family cat was looking at the bodies upon The Inspectors entry
The autopsy report showed this:
-Bob and Mary died from 2 things

4. Three Rooms

A murderer is condemned to death. He has to choose between three rooms.
The first is full of raging fires, the second is full of assassins with
loaded guns and the third is full of lions that haven’t eaten in 3 years.
Which room is safest for him?

5. An Unusual Paragraph

This is an unusual paragraph. I’m curious as to just how quickly you can
find out what is so unusual about it. It looks so ordinary and plain that
you would think nothing was wrong with it. In fact, nothing is wrong with
it! It is highly unusual though. Study it and think about it, but you still
may not find anything odd. But if you work at it a bit, you might find out.

6. Age

In 1990, a person is 15 years old. In 1995, that same person is 10 years old. How can this be?

7. Two Boxers

 Two boxers are in a match scheduled for 12 rounds. (Pure boxing only – no kicking, UFC takedowns, or anything else). One of the boxers gets knocked out after only six rounds, yet no man throws a punch. How is this possible?

8. A number Riddle

Children aged between 4 and 6 can solve this problem in less than 5 minutes. Can you?



9. The Lily Patch

In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half the lake?

10. Maple Syrup Spy Riddle

A German spy was in Canada trying to steal insider information on how to set up new Maple Syrup factories in Germany. He was being introduced to the operations manager of the biggest factory in Canada.
However, the manager was suspicious and decided to test him with a question before he trusted him. So he asked, what would you be sure to find in the middle of Toronto?
The spy thought fast and came up with an answer for the manager.

What did he say?
