Xiao Gang's family took part in family property insurance last year, with the insured amount of 20,000 yuan and the annual insurance premium rate of 0.3%, so the insurance premium paid by his family was 20,000 * 0.003 = 60 yuan. The insurance company lost 2940 yuan, and the Xiaogang family spent 2940+400=3340 yuan more than before. In addition, after deducting the insurance premium paid, 60 yuan is the total price of TV sets and bicycles, 3340-60=3280 yuan. The unit price ratio of bicycle and color TV is 1: 7, so the price of bicycle is only 1. The TV set is 3280-4 10=2870 yuan.
