Good.

Meh.

You misspelled Friday which makes the teaser needlessly obtuse.

This lateral thinking shit is the worst. It's just a guessing game.

1. The Emperor

You are the ruler of a medieval empire and you are about to have a celebration tomorrow. The celebration is the most important party you have ever hosted. You've got 1000 bottles of wine you were planning to open for the celebration, but you find out that one of them is poisoned.

The poison exhibits no symptoms until death. Death occurs within ten to twenty hours after consuming even the minutest amount of poison.

You have over a thousand slaves at your disposal and just under 24 hours to determine which single bottle is poisoned.

You have a handful of prisoners about to be executed, and it would mar your celebration to have anyone else killed.

What is the smallest number of prisoners you must have to drink from the bottles to be absolutely sure to find the poisoned bottle within 24 hours?

>What is the smallest number of prisoners you must have
A handful of prisoners cannot test 1000 bottles within 24 hours

retards

>>53408825
it must mean you don't need 1000 huh

this is probably a bad puzzle since it's pretty complicated

You still would if you wanted to be absolutely sure which bottle was poisoned. If you had 100 prisoners drink from 10 bottles each, you'd be able to narrow it down to 10 bottles, but you have no idea which one of the 10 bottles killed the guy. The more bottles a person drinks from the less specific information you get. If you had more time, you could have the prisoners go multiple rounds and narrow it down that way, but you don't have enough time.

If you need to be correct down to the bottle, the correct answer is 0. It says it would mar the celebration to have someone other than a prisoner die, but you don't need any prisoners to test bottles if you have 1,000 slaves. They all try a bottle, one of them dies, and you know exactly which bottle killed him. The only thing it's asking is the minimum number of prisoners you need to find the poisoned bottle. The stuff about how important the party is is just window-dressing.

also, the answer is a coffin

you can have the prisoners have empty stomachs, which will allow the poison to get absorbed within the 10 hour period therefore each prisoner drink out of a bottle every hour, meaning they can drink a max of 14 bottles each. You therefore need 72 prisoners and you can tell which bottle is the poisoned bottle depending on the prisoner that died and at what hour
>>
>>53409268
autism pls one prisoner can taste more than one bottle without dying you just need to smartly combine the the probabilities so that you use time to your advantage and have the least amount of people killed and the least amount of prisoners used
>>

It's not specific about the poison and how it affects the body. Stress can cause the stomach to empty directly into the small intestine; some of the prisoners might be women; fat vs. thin. You'd get closer, but you can't be absolutely sure which bottle without more testing.

>>53409584

How can you use fewer prisoners than zero? Did it say that it has to be a prisoner who dies? Why do you seem to consider the fact that you have 1,000 slaves to be useless information but assume 100% that it has to be a prisoner who dies?

The question is only "what is the smallest number of prisoners you must have," and the answer is obviously zero. It specifically tells you that you can run a test that is guaranteed to tell you exactly which bottle is poisoned in the time-frame, without assuming anything about empty stomachs or how the poison works.
