A Correct answer
Explanation

Total cost = (80 × 13.50) + (120 × 16) = Rs. 1080 + Rs. 1920 = Rs. 3000. For 20% profit, SP must be 120% of CP = Rs. 3000 × 1.20 = Rs. 3600. Per kg selling price = 3600/200 = Rs. 18. The mixture method requires finding weighted average cost first, then adding profit margin.
