Think well. As with any riddle, this one also has its own trick. Hint: The question you ask will cause the guards to point to the same door.

Correct answer

It is important to be able to formulate questions correctly in order to get the most beneficial answers. So, you need to ask the guards, "Which door did the other guard say leads to heaven?"

The trick is that an honest guard will point to the door that leads to Hell, because that's what a deceitful guard will do. Ask an unscrupulous guard the same question and he will also point to Hell, because he knows that a truthful guard will point to the door to Paradise.

In any case, both guards will show you the door to Hell, so you just go to the second one. There will be Paradise! How do you like this mystery? Did you manage to solve? Share your opinion in the comments.

8. What number will be next in this series: 1, 11, 21, 1211, 111221, 312211, ...

Answer 8:

13112221

· Each sequence of numbers is a verbal representation of the sequence that comes before it. So, for example, starting from one, the next sequence would be "one 1" or "11". It will be followed by the sequence "two 1" or "21" and so on.

· The first digit is 1 (amount) "1" (number from 0 to 9). So if you say "One 1", the next number will be "11". Now it turned out "two 1" or "21". After that "one 2 and one 1", which gives us 1211. Then "one 1, one 2 and two 1", which gives us 111221 and so on.

Difficult logic puzzle

You are standing in front of two doors. One door leads to Heaven and the other to Hell. There is a guard in front of every door. One of them always tells the truth, and the other lies all the time. However, you do not know which of them is an honest guard and which is a liar.

You can only ask one question to one guard to find the door to Paradise. What will be your question?

Riddle solution

Have you thought about the solution well? Here is the correct answer.

The question you need to ask is: If I ask another guard what door leads to Paradise, what will he say?".

No matter who you ask this question to, you will still get an answer that leads to Hell. Thus, you choose another door that will lead you to Paradise.

The Heaven and Hell puzzle first appeared in the 1986 film Labyrinth.

Here is the explanation for this puzzles if you haven't figured it out yet.

Let's say you ask an honest guard: " If I ask a liar guard what door leads to Paradise, what will he say?". In this case, the honest guard will tell you the answer of the liar. The answer of the liar will be the door to Hell, and the honest guard will point to the door to Hell.

Now imagine that we are asking this question to a liar. In other words, we ask him: " If I ask an honest guard what door leads to Paradise, what will he answer?"A liar will always give the opposite answer to an honest guard, because he always lies. And the opposite answer of an honest guard will be the door to Hell. And again you will be directed to the door to Hell.

And whatever the answer is, you will always choose the opposite door, and you will be 100 percent sure that you have chosen the door to Paradise.
