Last Updated : 18 Jan, 2023

You have five pieces of chain, each consisting of three links. You want to make one long chain of these five pieces. Breaking open a link costs 1 Rs, and welding an open link costs 3 Rs.

Is it possible to make one long chain of the five pieces, if you have just 15 Rs?

Solution:

Let us name the chains as 1, 2, 3, 4, 5 each having three links.

Take chain 1 and break open all three links: 1x3=3 Rs.
Take one open link to connect chain 2 and 3: 3 Rs.
Take another open link to connect chain 3 and 4: 3 Rs
Take third open link to connect chain 4 and 5: 3 Rs.

Now you have one long chain ready in only 12 Rs
