दिया गया है:

अंकित मूल्य (MP) = ₹517

अंकन = क्रय मूल्य पर 30%

लाभ = क्रय मूल्य पर 2%

प्रयुक्त सूत्र:

MP = CP × 1.30

SP = CP × 1.02

छूट % = ((MP - SP) / MP) × 100

गणना:

⇒ CP = 517 / 1.30

⇒ SP = (517 / 1.30) × 1.02 = ₹405.64

⇒ छूट % = ((517 - 405.64) / 517) × 100

⇒ छूट % = 21.54%

सही उत्तर विकल्प (1) है।
