Chain Logic

Below you can see several bits of broken chain. I have been told to join up all the pieces to make a complete necklace using all twenty links.








However, it is a very difficult job, and it takes one minute to cut one link, and two minutes to join it up again. How long will it take me to finish the necklace?


Watch this space for answer in a week.
