C Correct answer
Explanation

Total cost for 30 TV sets = 300,000. Cost of 15 sets = 15 * 9,000 = 135,000. Remaining cost = 300,000 - 135,000 = 165,000. Average of remaining 15 sets = 165,000 / 15 = 11,000.

AI explanation

The total cost of 30 TV sets is Rs. 300000, and the total cost of the first 15 TV sets is 15 multiplied by 9000, which equals Rs. 135000. The cost of the remaining 15 TV sets is 300000 minus 135000, giving Rs. 165000. Using the basic average formula, the average cost of these remaining 15 TV sets is 165000 divided by 15, which equals Rs. 11000.
