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?

Answer:

Yes, it's possible.

Step-by-step explanation:

Given:- We have 5 pieces of chain.

            Each chain consists of 3 links.

            Cost of opening a link = Rs.1

            Cost of welding an open link = Rs.3

To Find:- If it's possible to make one long chain of 5 pieces.

Solution:-

Let's number the chains as  1, 2, 3, 4, 5 each one of them having three links.

Now let's take chain 1 and break open all 3 links.

As we know, Cost of opening each link = Rs.1

∴ Cost of opening 3 links = 3 × 1 = Rs.3

Now take one open link and use it to connect chain 2 and chain 3.

Cost of welding = Rs.3

Now again using one open link connect chain 3 and chain 4.

Cost of welding = Rs.3

Now using the last open link to connect chain 4 and chain 5.

Cost of welding = Rs.3

Total cost = Cost of opening 3 links + 3(cost of welding open links)

                 = 3 + 3 + 3 + 3 = 15.

Hence, It is possible to make one long chain of 5 pieces in just Rs.15.
