Challenge your brain and find the most economic option to make the chain as per the riddle below.
I have 5. metal chain loops.
I want to join them and make a chain out of them.
It involves cutting and then welding the metal loops.
Cutting the ring would cost me Rs. 5 for each cut.
Welding each of the cuts would cost me Rs. 10.
What is the minimum cost to make the chain?

To join all the loops in one line to create a chain only 2 loops need to be cut.
so 2nd and fourth loop are cut and 1 and 3 loops are joined using 2nd while 3rd and 5th are joined using the fourth loop.
So in all I will have to make 2 cuts and 2 joints so the cost will be;
2 x 5 + 2 x 10 = 10 + 20 = 30
Answer = Rs.30
