If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100?

i think they takes 5 minutes

I think the same 5 is the correct answer

Ok, but how about this question: if 1 cleaning lady takes 6 hrs to clean a house, how long does it take 3 cleaning ladies?

Some will say 2 hrs, but that's not how it is - it will take 4 hrs because they will spend the 2 extra hrs just chatting instead of cleaning .... :)

Same number of machines make the same number of widgets, which uses the same time --> 5 minutes

hmm nope...!! I guess it is zero ...

ahahahah - if 5 machines make 5 of the same things in 5 min, then 1 makes 1 in 5 min and 100 make 100 in 5 min .... just like 1 woman makes 1 baby in 9 months & 1,000,000 women make 1,000,000 babies in 9 months .... got it?
