Our math teacher asked this from us.


You have no other containers. You can’t get any other things. It has to be exactly 1 liters in the container.

There are no measures in the containers.

Simple. Measure out 1 liters, then pour it into a container.
For extended OP, pour out the water from the 3 liter container then pour 1 liter into the container.

Pour out 4 liters from one and empty the other.

Problem solved.

Pour out 4 liters from one and 2 from the other.

Problem solved.

Read the fixed OP more carefully.

Go buy a liter bottle of water. Pour out all the other water and pour the bottle into one of the containers.

You dump it out?

He never said the 5 liter container was filled.
Easily pour 1 liter into it.

From where? Also, you’re unable to exactly know, that when it is 1 liter.

If you cant know when its exactly 1 liter, you will never know.

Why can’t you get other things? Are you locked in a room?

Fill the 5 liter container with 3 liters from the 3 liter container.

Refill the 3 liter container, fill the 5 liter container up to 5 liters.

You are left with 1 liter in the 3 liter container.

-5 + 3 + 3 = 1

As pointed out before you cannot use other things

What kind of bottles are you using? Let’s see…

If you push the 3 liter container down in the 5 liter, you’ll end up with 2 liters left in it (assuming both containers are filled). From there, the easiest way to solve it would be to split the water left in the 5 liter in half, but I don’t think that’s how the teacher wants you to do it. I’m trying to think of another way and coming up blank, though. D:

Edit: I was massively overthinking this, I was assuming we had no more water. Zshadow wins.

Is more water other things?

Then it’s not possible. The most you can do is exchange liters or pour them out, and any combination of 3 and 5 alone can not yield 1. :( You could get 2 liters in a bottle, but that’s about it.

I’m pretty sure water is a thing, as well as where ever you get this water from.

That’s why I think this is a trick question.

You are allowed to pour the water out.

Without measurements it is just guess work and thus near impossible.

Right, but you can’t fill it back up with more water?

If you can’t fill it back up, then you’re left working with 3 liters and 5 liters, so your only possibly outcomes are 2, 3, or 5.

I did this before. I’m pretty sure there was a third container.

Our math teacher got it somehow ending 1 liter being in the 3 liter container. He didn’t fill any of it but yet still he got 1 liter into the 3 liter container. :E

Wait, quoting the exact same words he wrote to the board:

Bob has a 5 liter container and a 3 liter container filled with water. How can he have 1 liter in one of the containers?

After that, our teacher explained that you can’t use e.g. any measures etc. And no, using more water is not considered other things, I guess.
