3 cuts are needed to cut a log into 4 parts.


So, one cut requires 6/3 = 2 minutes.



Next, 11 cuts are needed to cut a log into 12 pieces.


At the same rate of 2 minutes per cut, the required time is 2*11 = 22 minutes.   ANSWER

Solved.

Obviously, it is an entertainment problem, which you can consider as a joke Math problem, too.
