A businessman purchased 30 TV sets in ₹ 300000, If the average cost of 15 TV sets is ₹ 9000 then find out the average cost of remaining TV sets.
Correct Answer: ₹ 11000
Explanation:
Total cost of 30 TV sets = ₹ 300000
Total cost of 15 TV sets = 9000 x 15 = 135000
Total cost of remaining 15 TV sets = 300000 - 135000 = 165000 ∴ Average cost of remaining TV sets = 165000/15 = ₹ 11000
