Fill the 5L container and pour its contents into another 3L container; the amount left is 2L. Empty the 3L container, then pour the 2L that remains into it. After that, fill the 5L container again, and pour out the excess 1L into the 3L container – the amount left is 4L.
These well-known companies are really boring; they’re all full of silly riddles and trivial questions like that! Sigh~~~ You really can’t turn to HR when looking for a job!
I mainly focus on running ads and promoting events; feel free to watch and share
Can I say that this question puzzled me? :lol
Generally, anything that can’t be counted with one hand poses a challenge. :lol
I’m Blue Fatman; I don’t have any fingers.
It’s made so complicated; even 4L isn’t accurate
When I see a question like this, I usually don’t bother trying to think of an answer; it’s too time-consuming.
There is another method: first fill the 3L bottle, pour its contents into the 5L bottle, then fill the 3L bottle again and pour that water into the 5L bottle. At this point, the 5L bottle is full, while the 3L bottle still contains 1L of water. Pour out the water from the 5L bottle, transfer the 1L of water from the 3L bottle into the 5L bottle, and then fill the 3L bottle once more and pour its contents into the 5L bottle. In total, this amounts to 1L + 3L = 4L
