# After allowing 15% discount, the selling price of radio becomes Rs.255. The marked price is :

- Rs.600
- Rs.400
- Rs.300
- Rs.500

**Answer: (3) Rs.300**

**Explanation:-**

Selling price of a radio = Rs.225

Discount = 15%

Then, marked price of a radio = 225 x 100/(100 – 15)

= 225 x 100/75

= 225 x 4/3

= 75 x 4

= 300

Then, marked price of a radio is Rs. 300.

Hence, the correct answer is option (3) Rs. 300
