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 fiddly 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?

Lets give the number to the chains
1 2 3 4
5 6 7 8

Make a cut in 1 and fix it between 3 & 4 (one cut is suffice)
Make a cut in 2 and fix it between 7 & 8
Cut both the rings from 5 fix one of them between 4 & 8 and another between 6 & &7
Cut one open end of the 6 and fix it with 3.

Total Cuts = 5 i.e. 5 Min
Total Joints = 5 i.e. 10 Min
Total = 15 Min
