Thanks for stopping in to see if you or your coworker was correct… hopefully both of you were, or at least you got it correct!
Question: If it takes 5 elves 5 minutes to make 5 dolls, how long would it take 100 elves to make 100 dolls?
Answer: 5 Minutes; It takes one elf 5 minutes to make one doll. Therefore 100 elves making 100 dolls would still take 5 minutes!
