3 barrel question / logic puzzle

In summary, the conversation discusses a scenario where there are three barrels with incorrect labels and the task is to determine the minimum number of fruits needed to be drawn to correctly label them. The first barrel has 50 apples, the second has 50 oranges, and the third has a mix of both fruits, but the labels are incorrect. The minimum number of fruits needed is 52, assuming there is no information about the number of each fruit in the mixed barrel. The person in the conversation claims to have figured out the answer in under one minute and challenges the other person to do the same.

First of all, this is NOT a homework question.

So I give you three barrels, one has 50 apples, the second has 50 oranges, the third has 50 - a mixture of both apples and oranges.

However, I have intentionally placed the wrong labels on all of them.

Find the minimum number of fruits you need to draw to get the right labels! (also explain please)

(I have managed to figure out the answer in under one minute, see how fast can you figure it out.)

I think 52--if you have no information about how many of each fruit is in the mixed barrel.
 

What is the "3 barrel question" or logic puzzle?

The "3 barrel question" or logic puzzle is a well-known mathematical problem in which a person is given three barrels of different sizes and is tasked with accurately measuring a specific volume of liquid using only these barrels.

What are the rules of the "3 barrel question" or logic puzzle?

The rules of the "3 barrel question" or logic puzzle are as follows:

  1. The three barrels have capacities of 8, 5, and 3 liters respectively.
  2. There are no other measuring devices or containers available.
  3. Only whole numbers can be used to measure the liquid.
  4. The goal is to measure exactly 4 liters of liquid using these three barrels.

How do you solve the "3 barrel question" or logic puzzle?

There are multiple solutions to the "3 barrel question" or logic puzzle, but one possible solution is as follows:

  1. Fill the 8-liter barrel completely.
  2. Pour the contents of the 8-liter barrel into the 5-liter barrel, leaving 3 liters in the 8-liter barrel.
  3. Empty the 5-liter barrel and pour the 3 liters from the 8-liter barrel into it.
  4. Fill the 8-liter barrel again and pour enough into the 5-liter barrel to fill it completely (leaving 6 liters in the 8-liter barrel).
  5. Empty the 5-liter barrel and pour the 6 liters from the 8-liter barrel into it.
  6. Fill the 8-liter barrel again and pour enough into the 5-liter barrel to fill it completely (leaving 1 liter in the 8-liter barrel).
  7. Empty the 5-liter barrel and pour the 1 liter from the 8-liter barrel into it.
  8. Fill the 8-liter barrel one last time and pour all of its contents into the 3-liter barrel, which now contains 4 liters of liquid.
