I was screaming, "500 minutes! It's 500 minutes!" At my phone until the old guy made me realize that I should stay in school 🤦‍♂️

The old man was right, if 5 machines can make 5 donuts in 5 minutes, then each machine can make 1 donut in 5 minutes. Therefore, 100 machines can make 100 donuts in the same 5 minutes

it takes 5 minutes to make a single donut, but you're running 100 machines at the same time, it still takes 5 minutes

The smirk in his "wrong" at the last minute though 🤣

"someone ate the donut"

The old guy be like: Common sense not so common ig 💀

If you ask me a question like that,in the middle of street with camera on my face, I'll not be able to tell my name correctly

Tbf most people’s brain turns off when you shove a camera and mic in their face.

It's called math anxiety. If I'm asked any simple math problem (or something resembling one), in a public space I go into survival mode.

The smartest guy is the old man with an impeccable sense of style.

"it takes 9 pregnant women, 9 months to carry out 9 babies - how long does it take for 100 pregnant women to carry out 100 babies...?"

Yes the old guy actually has some common sense

When it comes to math, there are only three kinds of people. Those who can do it, and those who can’t.

The answer is 5 minutes. The fact that it takes 5 machines 5 minutes to make 5 donuts means that it takes 5 minutes to make each donut. So that means that if 100 machines were making 1 donut each to have a total of 100 donuts, it would still take 5 minutes.

The question's wording is well-intentioned, but, a simple "at the same time" would probably have cleared this one up for at least half the group.

The old "wise" man- "Experience, son, Experience" 😇😁

The anxiety of being asked this in a public situation on the spot and on camera definitely impacts people's ability to answer the question confidently

It would still take 5 minutes to make 100 donuts with 100 machines.

Old guy was the smartest, love his explanation too

"Did those 5 machines produce 5 doughnuts in parallel or in serial?" is the appropriate response.
