Answer: (3) Rs. 500

Solution:-
Le the cost price of a radio be X.
A radio is sold at a gain of 16%. If it had been sold for Rs. 20 more, 20% would have been gained.
Then, (20 – 16) x X/100 = 20
X x 4/100 = 20
X /25 = 20
X = 20 x 25
X = 500

Then, the cost price of a radio is Rs. 500.

Hence, the correct answer is option (3) Rs. 500.
