Can you crack these 2 logical puzzles?
TLDRThe video script presents two intriguing logical puzzles that challenge the viewer's analytical skills. The first puzzle involves cracking a four-digit code with clues that indicate the correctness and position of the digits. Through a process of elimination based on the clues, the correct code is deduced to be 3841. The second puzzle features a conversation between two logicians, A and B, who each secretly choose a number from 1 to 30. Through a series of questions and responses, they logically deduce each other's numbers. B ultimately determines A's number is 4, based on the rules of even and odd numbers, and the concept of multiples. The video concludes with a nod to the viewers' problem-solving abilities and an invitation to join future episodes, emphasizing the community aspect of the channel.
Takeaways
- 🔐 The first puzzle involves figuring out a four-digit code using a set of clues that provide information about the position and correctness of the digits.
- 🔍 Starting with the clue where nothing is correct (6507) helps to eliminate possibilities and provides a solid foundation for solving the puzzle.
- 📌 By process of elimination and using the clues, it's determined that the digits 2 and 8 are correct, but 9 and 5 are not.
- 🧩 The position of the correct digits is deduced through the clues, leading to the conclusion that the correct code is 3841.
- 🤔 The second puzzle is a logical deduction game between two logicians, A and B, who each pick a whole number from 1 to 30.
- 🗣️ A series of questions and answers between A and B allows them to eliminate possibilities and deduce each other's numbers through logical reasoning.
- 🙅♂️ B's initial 'I don't know' response to whether their number is double A's indicates that B's number must be even.
- 🙅♀️ Similarly, A's 'I don't know' responses help to narrow down the possible numbers for B's number and vice versa.
- 🔢 It is concluded that A's number is a multiple of four and B's number is between 2 and 14.
- 💡 B's final statement of knowing A's number is possible because the process of elimination leaves only one number that fits all the criteria: A's number is four.
- 🎉 The puzzles demonstrate the power of logical deduction and the importance of process of elimination in problem-solving.
- 📚 These puzzles are examples of the kind of logical and analytical challenges that can be found in online communities like Reddit's riddles section.
Q & A
What is the first logical puzzle about?
-The first logical puzzle is about figuring out a four-digit code using a series of clues that indicate which numbers are correct and incorrect, and their positions.
What is the significance of the clue '6507' in the first puzzle?
-The clue '6507' indicates that none of the digits are correct, which helps to eliminate certain possibilities for the four-digit code.
How does the clue '9285' help in solving the first puzzle?
-The clue '9285' indicates that one number is correct but in the wrong position, which helps to narrow down the possible correct numbers to 2 or 8, and confirms that 9 is incorrect.
What does the clue '1,937' reveal about the correct numbers and their positions?
-The clue '1,937' reveals that two numbers are correct but in the wrong positions, confirming that 1 and 3 are the correct numbers.
What is the final four-digit code determined in the first puzzle?
-The final four-digit code determined in the first puzzle is 3841.
What is the second logical puzzle about?
-The second logical puzzle involves two logicians, A and B, who each secretly pick a whole number from 1 to 30. They engage in a conversation that allows them to deduce each other's numbers through a series of questions and answers.
Why does B's initial response of 'I don't know' to A's question imply that B's number is even?
-If B had an odd number, they would be able to definitively say that it is not double A's number, as no odd number can be double another odd number. Since B says 'I don't know,' it suggests that B's number could be double A's number, which means it must be even.
What is the significance of A's response 'I don't know' to B's question 'Is your number double mine?'?
-A's response indicates that A's number could be a multiple of four, as it would need to be even to possibly be double B's number.
How does B deduce A's number after the conversation?
-B deduces that A's number is four because it is the only number that fits all the conditions of their conversation: it is a multiple of four, it is between 2 and 14, and it is not half of any of the remaining possible numbers for B.
What is the key to solving the second puzzle?
-The key to solving the second puzzle is the process of elimination based on the information given in the conversation between A and B, and understanding the implications of their responses.
What does the second puzzle demonstrate about logical deduction?
-The second puzzle demonstrates how logical deduction can be used to narrow down possibilities and arrive at a single solution through a series of questions and answers, even when the initial information is limited.
Outlines
🔐 Four-Digit Code Puzzle
The first paragraph presents a logical puzzle involving a four-digit code. The puzzle provides clues to help deduce the correct sequence of the code. The clues are as follows: '9285' indicates one number is correct but in the wrong position, '1937' suggests two numbers are correct but in the wrong positions, '5201' confirms one number is correct and in the right position, '6507' indicates nothing is correct, and '8524' reveals two numbers are correct but in the wrong positions. By analyzing these clues, the paragraph leads to the solution that the correct four-digit code is '3841'.
🧐 The Logicians' Number Deduction Puzzle
The second paragraph describes a problem-solving scenario between two logicians, A and B, who each secretly pick a whole number from 1 to 30. They engage in a conversation to deduce each other's numbers without directly revealing them. Through a series of questions and answers, they manage to narrow down the possibilities based on the logic of doubling and halving numbers. The key steps include A asking if B's number is double theirs, B responding 'I don't know,' and further back-and-forth questions that lead to B deducing A's number is four. The puzzle demonstrates logical reasoning and the process of elimination to arrive at the conclusion.

Highlights
Walker introduces two logical puzzles for the audience to solve.
The first puzzle involves figuring out a four-digit code with given clues.
The second puzzle is a conversation between two logicians, A and B, where they deduce each other's numbers without knowing them directly.
For the first puzzle, the clue '6507 nothing is correct' is used to eliminate possibilities.
The clue '9285 one number is correct but in the wrong position' helps to narrow down the correct numbers.
The clue '1937 two numbers are correct but in the wrong positions' provides further insight into the correct digits.
The clue '5201 one number is correct and in the right position' confirms the position of the digit '1'.
The correct four-digit code is deduced to be '3841'.
In the second puzzle, A's question about doubling numbers helps B deduce that their number must be even.
B's response of 'I don't know' to A's question about halving numbers indicates that B's number is between 2 and 14.
A's final 'I don't know' response to B's question about halving numbers leads B to deduce that A's number is a multiple of four.
B concludes that A's number is four, as it's the only number that fits all the given conditions.
The logical deductions made by B are based on the process of elimination and the rules of even and odd numbers.
