Puzzle has been solved!

No Comment - Post a comment

Few days ago, I posted a puzzle whether a bottle poisoned wine can be identified among the batch of 1000 bottles within 24hours.

One of them was anonymous, the other was fatboyho.

Quoting one of solution here for all.
solving this puzzle requires the understanding of the binary system. each 'pattern' in the binary system corresponds to one unique number.

the 1st prisoner will take the 1st number of the binary (so he'll be taking a sip out of bottles 1,3,5,7...all the way to 999).

the 2nd prisoner will take the 2nd number of the binary (bottles 2,3,6,7,10,11...).

the rest of the prisoners will take their respective places in the binary. (3rd prisoner take 3rd number in binary and so on so forth)

so let's say bottle 736 is the one with the poison. the binary for 736 is 0101110000. therefore, prisoners 5,6,7,9 will be dead by the next day.
Cheers.

Stupid Kids! ARGH

Was at AMK library for the past 2 days. And for the consecutive 2 days there were disturbing kids who just can't keep their mouth shut!

The 1st day was a group of 4 poly guys who sat behind me about 2m away. They arrived in the morning and chit chat their way till night. Are they here to study or chat? The 2nd day was a group of Secondary school malay kids who brought a notebook along and just giggle and chatting in front of the screen. What the hell? Library is no longer the way before where everyone has to whisper even at close contact.

Anyway, posted a little puzzle few days ago titled "Identify the poisoned wine" here. Shall reveal a much cleaner and easy to execute solution during the weekends. I know you can't wait, so do I lol

Identify the poisoned wine

CAN YOU SOLVE THIS PUZZLE?

A king has 1000 bottles of wine. An assasin tried to poison the wine. The king's guards caught the assasin after he poisoned only one bottle, but they did not know which bottle was poisoned.

It is known however that the poison is so powerful that even a tiny bit of the poisoned wine will kill, and it is known also that the poison will only kill after 24 hours. The king order you, his advisor, to get some of the criminals in the dungeon to test the wines for him. The king expects to find out the result the next day, essentially 24 hours after the testers drink the wine.

Now the simplest way is if 1000 criminals were available, just get them to each drink a little bit from each of the 1000 bottles. Hence, the poisoned bottle will be identified when one particular tester, out of the thousand testers, dies the following day. However, only 10 criminals is imprisoned in the dungeon on that particular day!

Is there a way to identify the poisoned bottle by the following day using only 10 testers? What is the method?"

Einstein wrote this quiz last century. He said that 98% of the people in the world cannot solve the quiz.

  • There are 5 houses in 5 different colors
  • In each house lives a person with a different nationality
  • These 5 owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet
  • No owners have the same pet, smoke the same brand of cigar or drink the same drink.
Here's the question: Who owns the fish?
  1. The Brit lives in a red house
  2. The Swede keeps dogs as pets
  3. The Dane drinks tea
  4. The green house is on the left of the white house
  5. The green house owner drinks coffee
  6. The person who smokes Pall Mall rears birds
  7. The owner of the yellow house smokes Dunhill
  8. The man living in the house right in the middle drinks milk
  9. The Norwegian lives in the first house
  10. The man who smokes Blend lives next door to the one who keeps cats.
  11. The man who keeps horses lives next door to the man who smokes Dunhill
  12. The owner who smokes Blue Master drinks beer
  13. The German smokes Prince
  14. The Norwegian lives next to the blue house
  15. The man who smokes Blend has a neighbor who drinks water
With these 15 clues the problem is solvable.

Used 3 papers before finally solve it.
