Riddles have been used thousands of years ago to measure how smart and creative an individual is in solving puzzling situations. The Greeks, Egyptians, and even American Indians, all loved riddles – they were handed from one generation to another, evolving into modern brainteasers. Here are 5 riddles you can’t solve in less than 5 minutes! Before we start our list, don’t forget to subscribe to our channel by clicking the subscribe button below!
Fork in the Road
You stand at a fork in the road – next to each of the two forks, there stands a guard. The first path leads to paradise and the other, leads to death. Both paths on the other hand, look the same, so there is no way to figure out which one’s which. It’s the same with the guards – you don’t know which one always tells the truth, and the one who always tells lies.
Before you can choose the path, you have the permission to ask one guard a question to discover which one leads to paradise. So, what question would you ask to guarantee your path to paradise?
Answer: Which door would the other guard say leads to paradise?
Reason: If you ask this question to each one of them, they will always end up picking the wrong door.
The Teresa Riddle
Here’s a riddle from DJ Kennedy Jones that circulated the web a few years ago.
If Teresa’s daughter is my daughter’s mother, what am I to Teresa? Am I her grandmother, mother, daughter, granddaughter, or am I Teresa?
So, what do you think is the answer to this simple riddle? While most people would say “granddaughter”, the correct answer for this riddle is “daughter”. When a lady says the “my daughter’s mother”, she is referring to herself. If we rephrase the riddle, it will go something like – “If Teresa’s daughter is me, what am I to Teresa?”
The Bridge Riddle
This bridge riddle from Ted-ED is a modernized version of The Midnight Train riddle, dating back to 1981 in riddles and puzzle books.
The premise is that you took an internship in a remote mountain lab, and an accident suddenly happened – it released mutant zombies and you need to get away fast. With you are the janitor, the lab assistant, and an old professor. You’ve gotten a head start, but there is only one way to safety – across an old bridge spanning a massive gorge.
You can dash across in a minute, while the lab assistant takes two minutes. The janitor needs five minutes, and the old professor needs 10 minutes to cross the bridge. By the professor’s calculations, the zombies will catch up to you in just over 17 minutes. Unfortunately, the bridge can only hold two people at a time. To make matters worse, it’s dark outside that you can barely see, and you only have one lantern to illuminate a small area.
How can every one of you get to safety in less than 17 minutes? Remember, that no more than 2 people can cross the bridge together, and anyone crossing must hold the lantern.
First, you need to cross the bridge with the lab assistant – this takes 2 minutes.
Then, the lab assistant will come back with the lantern, which also takes 2 minutes.
Then, the professor crosses the bridge with the janitor, taking up 10 minutes.
Now, you need to get to the lab assistant with the lantern, taking 1 minute.
Finally, you can cross the bridge with the lab assistant again, taking 2 minutes.
The total travel time will sum up to 17 minutes!
When is Cheryl’s Birthday?
Albert and Bernard just become friends with Cheryl, and they want to know when her birthday is. Cheryl, on the other hand, gave them a list of 10 possible dates.
May 15, May 16, May 19, June 17, June 18, July 14, July 16, August 14, August 15, and August 17.
Cheryl then, tells Albert and Bernard separately the month and the day of her birthday respectively.
Albert says – I don’t know when Cheryl’s birthday is, but I know that Bernard does not know too.
Bernard says – At first, I don’t know when Cheryl’s birthday is, but I know now.
Albert then says – Then, I also know when Cheryl’s birthday is.
So, when is Cheryl’s birthday?
Answer: July 16
Reason: We need to figure out if Albert knows the month or the day. If he knows the day, there’s no chance that Bernard knows the Birthday, so it’s a must that Albert knows the month. The first statement shows that Albert is sure that Bernard doesn’t know her birthday, so May and June should be ruled out. In other words, if Albert had May or June, then he can’t be sure that Bernard doesn’t know, since Bernard could have had 18 or 19.
Following that statement, Bernard now knows that May and June are ruled out. He then, is able to know which month it is. So it must be July 16, August 15, and August 17 – ruling out August 14 as then he can’t know.
Since Albert subsequently can also be sure of the date, he must know that it’s July. If it’s August, he can’t be sure as there is August 15 and 17, making July 16 as the best answer.
Let’s finish up with this clever riddle from Einstein. He even said that 98% of the world could not solve it!
