Correct answer: (C) 80%
Let CP of 1 article = ₹1, MP = ₹m. Customer pays for 16 at 15% discount but gets 18 articles. Revenue = 16 × 0.85m = 13.6m for 18 articles' worth of CP = 18. Gain 36% → Revenue = 1.36 × 18 = 24.48. So 13.6m = 24.48 → m = 1.8. MP is (1.8−1)/1 × 100 = 80% more than CP.

सही उत्तर: (C) 80%
मान लें 1 वस्तु का CP = ₹1, MP = ₹m। ग्राहक 16 वस्तुओं का भुगतान 15% छूट पर करता है लेकिन 18 वस्तुएँ पाता है। आय = 16 × 0.85m = 13.6m; 18 वस्तुओं का कुल CP = 18; 36% लाभ पर आय = 1.36 × 18 = 24.48। अतः 13.6m = 24.48 → m = 1.8। MP, CP से (1.8−1)/1 × 100 = 80% अधिक है।
