C Correct answer
Explanation

Cost of A+B = 120, ratio 7:5 means A=70, B=50. C = B-10 = 40. Quantities in ratio 3:5:7. Total cost for 15 units = 3*70 + 5*50 + 7*40 = 210 + 250 + 280 = 740. Total profit needed 40% = 740 * 1.4 = 1036. One-fifth sold for 80 (3 units * 80 = 240). Remaining 12 units need to be sold for 1036 - 240 = 796. Price = 796 / 12 = 66.33.
