The cost price of a radio is ₹ 600.5% 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

Options

A. ₹ 684.50
B. ₹ 704 .50
C. ₹ 724.50
D. ₹ 664.50

Answer

To find the selling price of the radio, we will follow these steps:

### Step 1: Calculate the Transportation Cost
The cost price (CP) of the radio is ₹600. We need to calculate 5% of this cost price for transportation.

\[ \text{Transportation Cost} = 5\% \text{ of CP} = \frac{5}{100} \times 600 = 30 \]

### Step 2: Calculate the Total Cost Price
Now, we will add the transportation cost to the original cost price to find the total cost price.

\[ \text{Total Cost Price} = \text{CP} + \text{Transportation Cost} = 600 + 30 = 630 \]

### Step 3: Calculate the Desired Profit
Next, we need to calculate the profit that we want to make, which is 15% of the total cost price.

\[ \text{Profit} = 15\% \text{ of Total Cost Price} = \frac{15}{100} \times 630 = 94.5 \]

### Step 4: Calculate the Selling Price
Finally, we will find the selling price (SP) by adding the profit to the total cost price.

\[ \text{Selling Price} = \text{Total Cost Price} + \text{Profit} = 630 + 94.5 = 724.5 \]

### Conclusion
The selling price of the radio must be ₹724.5.
