Question

A diamond broken in the ratio 3:4:7:6 . The cost of the diamond is directly proportional to square of its weight. If the diamond broken in the ratio 5:3:4:3 then there would have been a loss of rs.3450 . Find the initial cost of diamond .​

Answer 1

Step-by-step explanation:

ci=k(3*2+4*2+7*2+6*2)=110k

c2=k(5*2+3*2+4*2+3*2)=59k

loss=(ci-c2)=51k=3450

k=67.64

ci=7441
