# After allowing discount of 20%, a radio is available for Rs. 1200. Its marked price was:

- Rs.1800
- Rs.1400
- Rs.1550
- Rs.1500

**Answer: (4) Rs. 1500**

**Explanation:-**After allowing discount of 20%, a radio is available for Rs. 1200.

Then, the marked price = 1200 x 100/80

= 1200 x 5/4

= 300 x 5

= Rs. 1500

Then, the marked price is Rs. 1500

Hence, the answer is (4) Rs. 1500.
