Q. 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 :
Answer: 724.50 Rs
Notes: Actual C.P. of radio = $latex = 600 + \frac{600\times 5}{100} = 630 Rs.&s=1$ ∴ Required S.P. = $latex = \frac{630\times 115}{100} = 724.50 Rs.&s=1$ Hence option [D] is the right answer.
