दो छूट के बीच का अंतर = 220 रुपये
छूट (D) = 40%
क्रमिक दो छूट,
छूट (D1) = 30%; छूट (D2) = 30%
प्रयुक्त सूत्र:
समतुल्य छूट (D) = D1 + D2 - (D1 × D2)/100
गणना:
समतुल्य छूट (D) = 30 + 30 - (30 × 30)/100
⇒ 60 - 9 = 51%
छूट में अंतर = (51 - 40)% = 220
⇒ 11% = 220
⇒ 1% = 20 रुपये
अंकित मूल्य (M.P) = 100% = 20 × 100 = 2000 रुपये
∴ सही उत्तर 2000 रुपये है।
