D Correct answer
Explanation

Total cost = 80 × 13.5 + 120 × 16 = 1080 + 1920 = Rs 3000. Total weight = 80 + 120 = 200 kg. Cost price per kg = 3000/200 = Rs 15. For 40% profit, selling price = 15 × 1.40 = Rs 21 per kg. Option D is correct. Options A, B, and C represent different percentage gains (approximately 20%, 33%, and 47% respectively) but not the required 40%.
