Top 5 Ted-Ed Riddles with Explanations

Now, let’s explore some of the most intriguing Ted-Ed riddles and their solutions.

1. The Bridge Crossing Riddle

The Challenge

Four people need to cross a bridge at night. They have one flashlight, and the bridge can only hold two people at a time. Each person takes a different amount of time to cross:

• Person A takes 1 minute
• Person B takes 2 minutes
• Person C takes 5 minutes
• Person D takes 10 minutes

When two people cross together, they must go at the slower person’s pace. Can they all cross in 17 minutes or less?

The Solution

To minimize time, the group must use an efficient strategy:

1. A and B cross first (2 minutes).
2. A returns with the flashlight (1 minute).
3. C and D cross together (10 minutes).
4. B returns with the flashlight (2 minutes).
5. A and B cross again (2 minutes).

Total time: 2 + 1 + 10 + 2 + 2 = 17 minutes.

2. The Prisoner Hat Riddle

The Challenge

Four prisoners are lined up in a row, each wearing a hat that is either black or white. They can only see the hats of the prisoners in front of them but not their own. They must determine their hat color to be set free. They cannot talk to each other, and they only get one chance to guess correctly.

Can they escape?

The Solution

The trick is logical deduction. The last person in the row sees the two hats in front of him. If they are the same color, he knows his must be different. If they are different, he remains silent so the next person can deduce their hat color. Using this strategy, at least one prisoner will always escape.

3. The Three Gods Riddle

The Challenge

There are three gods: Truth, Lie, and Random. Truth always tells the truth, Lie always lies, and Random answers randomly. You can ask three yes/no questions, but they will answer in their own language, which you do not understand.

How can you determine which god is which?

The Solution

The key is to ask questions where the answer remains consistent, regardless of whether they tell the truth or lie. A famous trick is asking:
“If I were to ask the other god whether you are Truth, what would they say?”
This forces a logical contradiction that helps identify each god.

4. The Dark Coin Riddle

The Challenge

You are given 100 coins, and 10 are heads-up while the rest are tails. You are blindfolded and must separate the coins into two piles with the same number of heads-up coins.

How can you do it?

The Solution

Take any 10 coins from the pile and flip them. This guarantees that both piles have the same number of heads-up coins, due to probability balancing.

5. The Rope Burning Riddle

The Challenge

You have two ropes, each of which takes exactly 60 minutes to burn. However, they burn at an uneven rate—some parts might burn faster than others.

How can you measure 45 minutes using only these ropes and a lighter?

The Solution

1. Light Rope 1 from both ends and Rope 2 from one end.
2. When Rope 1 finishes burning (30 minutes), light Rope 2 from the other end.
3. Since Rope 2 now has only 30 minutes left and is burning from both ends, it will finish in 15 minutes.

Total time: 30 + 15 = 45 minutes.

6. The False Coin Riddle

The Challenge

You have 12 identical-looking coins, but one of them is either heavier or lighter than the others. You also have a balance scale, and you can use it only three times to determine which coin is different and whether it is heavier or lighter.

How do you find the false coin in three weighings?

The Solution

This is a classic logic puzzle that requires dividing the coins into groups. Here’s how you solve it:

1. First Weighing: Divide the 12 coins into three groups of four. Place four coins on each side of the scale.

   • If the scale balances, the odd coin is in the group not on the scale.
   • If the scale tips, the odd coin is in the heavier or lighter group.

2. Second Weighing: Take the group suspected of having the odd coin and weigh three of them against three normal coins.

   • If the scale tips, you know the odd coin is one of the three and whether it is heavier or lighter.
   • If the scale balances, the odd coin is the one left out, and you now know whether it is heavier or lighter.

3. Third Weighing: Use a simple comparison of two of the three suspected coins to determine which one is the false coin.

Using this strategy, you can always find the false coin in just three weighings!

7. The Poisoned Wine Riddle

The Challenge

A king has 1000 bottles of wine, and one of them is poisoned. The poison is so deadly that one sip will kill a person in exactly 24 hours.

The king only has 10 prisoners and exactly 24 hours to find the poisoned bottle before a grand feast. How can he do it?

The Solution

The key is to use binary representation and strategically have prisoners sip from multiple bottles.

1. Number all bottles from 1 to 1000 in binary form.
2. Assign each prisoner to drink from bottles corresponding to specific bits in the binary numbers.
   • For example, if a bottle’s number in binary is 101, the 1st and 3rd prisoner will sip from it.
3. After 24 hours, check which prisoners died.
4. Their deaths will form a binary number, which corresponds to the poisoned bottle.

Since 10 prisoners can create 2¹⁰ (1024) unique combinations, this method allows identification of the poisoned bottle within the given time.

8. The Time-Traveling Assassin Riddle

The Challenge

You are a time traveler sent back to prevent an assassination. However, you don’t know who the assassin is or their target. You have one chance to stop the crime, and you can only make one move.

How do you ensure the assassin fails without knowing their identity?

The Solution

This is a lateral thinking puzzle. Instead of trying to find the assassin or the victim, the best move is to stop time at the exact moment before the crime occurs. This prevents the assassination altogether, making identification unnecessary.
