1. I have five sections of a necklace-each section consisting of
four links. I took the sections to a goldsmith and asked him to give me
an estimate to join the 5 sections - into a one piece necklace. The
goldsmith wanted-Re.1 to cut open a link and Re. 1 to solder
it together again.

What is the cheapest method and how much should it cost me to get the five pieces joined together into one full necklace?
