There are 4 gold chain. 1 has 5links, other has 4 links and the other 2 have 3 links.

bake whole bracelet.
Choose the correct answer:
A) 3.50 rupees B) 4.50 rupees C) 4.80 rupees D) 5.50 rupees E) 6.50 rupees
Let,the shape of the bracelet is closed circle.[It is supposed to assume]   gold chain with 5 links: A_ _ _ _ _B   gold chain with 4 links: C_ _ _ _D   gold chain with 3 links: E_ _ _F   gold chain with 3 links: G_ _ _H   We,generally hold a common notion that since there are 4 gold chains and since we are to make a closed circular shaped bracelet, so,we have to join the ends namely :(B,C),(D,E),(F,G),(H,A),i.e, total 4 links have to be broken and further joined,i.e, total cost will then be 4(1+.50)= 6 rupees.   But,now we will tackle the problem in a different way.   Let, all the 3 links of GH chain are broken.   Then,   with the help of 1st broken link, B and C ends are joined.   with the help of 2nd broken link, D and E ends are joined.   and,   With the help of the remaining broken link, F and A ends are joined.   So, the above mentioned method explains us that breaking only 3 links and subsequently joining two free ends with each link facilitates us to make a whole closed circular shaped bracelet.   Therefore,the cost in this case : 3*(1+.50) = 3*(1.50)=
