Explanation

City C: Radio(32680) + CD(48300) + I-Pod(14960) = 95940. Cell(50000) + MP3(21300) + Stereo(36200) = 107500. Ratio 95940 : 107500 = 9594 : 10750 = 4797 : 5375.

AI explanation

Add the total users for radio, CD player, and I-pod in city C: 32680 + 48300 + 14960 = 95940. Next, add the users for cell phone, MP3 player, and stereo systems in city C: 50000 + 21300 + 36200 = 107500. Form the ratio of these two totals, which is 95940 to 107500. Divide both numbers by their greatest common divisor of 20 to get the simplified ratio of 4797 to 5375.
