The price of precious stone is directly proportional to square of its weight. what will be the loss incurred if a stone weighing 28gm and costing 28,000 breaks into two pieces whose weights are in the ratio 15:13?  Choose the correct choice from the following options
A) 13958.58  B) 13928.58  C) 14000  D) 13562.42  E) None of these
Explanation :   Let price = p,weight = w.   p=k w^2 ---------eq(1) [here k is a constant taken]   As it is given dat price is directly proportional to weight   given w = 28,p = 28000   So from eq(1),k=1000/28   Now the broken pieces are 15gm nd 13gm   13928.58y putting the values of w and k in eq(1) we get   p1=8035.71(for w=15)   p2=6035.71(for w=13)   Total cost for broken pieces = (8035.71+6035.71)=

14071.42   So the loss=(28000-14071.42)=

<output>13_928.58</output>
13928.58   Answer : 13928.58
