B Correct answer
Explanation

Total cost = (10 * 1200) + (6 * 600) = 12000 + 3600 = 15600. Total weight = 16 kg. Cost per kg = 15600 / 16 = 975. Selling price at 20% profit = 975 * 1.2 = 1170.

AI explanation

Using the weighted average formula, the cost price of the blended coffee per kg is ((10 times 1200) plus (6 times 600)) divided by 16. This equals 15600 divided by 16, which gives a cost price of Rs. 975 per kg. Applying the profit percentage formula, the selling price is 975 multiplied by 1.20, resulting in Rs. 1170 per kg.
