Ok, here is another great riddle from Maria Konnikova.
And don’t miss my favorite riddle.
Can you get it without looking at the answer?
Question
If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets?
Answer
If 5 machines take 5 minutes to make 5 widgets, then the output of 1 machine is 5 minutes to make 1 widget.
So let’s restate the question for clarity:
If it takes 1 machines 5 minutes to make 1 widgets, how long would it take 100 machines to make 100 widgets?
The answer is 5 minutes.
1 machine makes 1 widget every 5 minutes.
2 machine makes 2 widgets every 5 minutes.
3 machine makes 3 widgets every 5 minutes.
Etc.
