six wolves catch six lambs in six minutes. How many wolves will be needed to catch sixty lambs in sixty minutes. The answer is not sixty.

Question

Please explain how you got your answer. Thank you.

Answer 1

This is a classic! If in 6 minutes 6 wolves got 6 lambs it means that each of them caught one lamb so it takes one wolf 6 minutes to catch a lamb. 60 minutes has 60/6 = 10  six minute intervals so in 60 minutes one wolf can catch 10 lambs. If you want to catch 60 lambs in that time you will need 60/10 = 6 wolves.
