Answer:
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
