This is another puzzle I picked up from Brilliant.org posted by Can Hou and the puzzle is originally from Oxford University interviews.
I have a pint of orange juice. I drink half of it and then give it to you. You drink half of what’s remaining, and then pass it back to me. I drink half of what’s remaining and then give it to you. This process continues forever. How many pints did I drink in total?
As always, please send your answers directly to me at firstname.lastname@example.org. If you like the puzzle, please share it with others. If you have interesting puzzles to share, please send them to me at my e-mail given above.
Happy drinking (only water)!
