The cost price of a radio is 600 Rs. The 5% of the cost price is charged towards transportation. After adding that, if the net profit to be made is 15%, then the selling price of the radio must be :
[A]664.50 Rs.
[B]684.50 Rs.
[C]704.50 Rs.
[D]724.50 Rs.

724.50 Rs.
Actual C.P. of radio =
= 600 + \frac{600\times 5}{100} = 630 Rs.
∴ Required S.P. =
= \frac{630\times 115}{100} = 724.50 Rs.
Hence option [D] is the right answer.
