You have eight balls and a set of scales. Seven of the balls weigh identically, the eighth is heavier. Using the fewest steps possible, how do you find the heavy ball?

Split them in half and put on scale, then split heavier half again. Then once more. Easy.

the heavier one will leave a slightly deeper dent in the wall on the way out.

ud think theyd want an answer that can generalize to any arbitrary number of balls: 1.) put them in op's mom's mouth 2.) ask her which one is heaviest

yea might take a third step if you get unlucky here though: o/ø o because you'll have to figure out which of the two is weighted more unless I'm mistaken.

Insert them all into your anus, jump up and down for a bit, the First one you poop out is heaviest, because Science.

Moridin920 posted:yea nah, when you have 3 balls (one of the heavy ones was in one of the initial sets of 3) you weigh 2 , if they're equal the third ball is the heavy one if they are not equal then the heavy one is the heavy one, it's one step either way.

Moridin920 posted:yea either the scales balance which means it's the odd ball or they don't which lets you identify the heavier ball that way. still two steps neat question edit: cool

I saw o/ø o and didn't realize you just weigh 2 and figure it out based on that result and like a retard I missed the extra space and saw 'weigh the set of 3 with 1 ball against 2.'

After some quick google'ing it looks like you 3 steps: 1) Pick one of the balls at random and use it to bludgeon the interviewer to death. 2) Eat their heart thus gaining their strength, entire worldly possessions, and most importantly position in the company. 3) if the position you were going for is preferable than the one the interviewer had, as the new official interviewer give yourself that job. If not keep your current newly occurred interviewer job.

I think it'd be really funny to design a puzzle like this where there was no actual clever solution. Like here you're supposed to immediately see the 'keep dividing the set in 2 and remove the lighter set' approach that results in 3 steps and from there you are supposed to realize there is a less obvious way to do it in fewer steps so you look for it and eventually come up with 3 and 3 trick but like it'd be great if there were a similar puzzle where there wasn't actually a way to do it better than the obvious solution and it just made people waste time looking for one.

Platinum pubes. Edit for more substance: no one is arguing my method yet, proof of its obvious superiority, also gives the interviewer something to think on: if you can solve problems with your rear end, just think what your brain can do. staberind fucked around with this message at 20:17 on Jul 17, 2015 |

this is all a hypothetical exercise anyway since we all know goldman sachs hires based on your ability to gently caress over thousands of people for a quarter point stock bump and also your ability to have been born with the right connections
