दिया गया:

अंकित मूल्य (MP) = ₹1,600

क्रय मूल्य (CP) = ₹1,600 ÷ (1 + 25/100)

छूट = 16%

प्रयुक्त सूत्र:

लाभ प्रतिशत = \(\frac{Selling Price - Cost Price}{Cost Price} × 100\)

विक्रय मूल्य (SP) = अंकित मूल्य × (1 - छूट/100)

गणना:

क्रय मूल्य = ₹1,600 ÷ 1.25

⇒ क्रय मूल्य = ₹1,280

विक्रय मूल्य = ₹1,600 × (1 - 16/100)

⇒ विक्रय मूल्य = ₹1,600 × 0.84

⇒ विक्रय मूल्य = ₹1,344

लाभ = विक्रय मूल्य - क्रय मूल्य

⇒ लाभ = ₹1,344 - ₹1,280

⇒ लाभ = ₹64

लाभ प्रतिशत = \(\frac{Profit}{CP} × 100\)

⇒ लाभ प्रतिशत = \(\frac{64}{1280} × 100\)

⇒ लाभ प्रतिशत = 5%

∴ सही उत्तर विकल्प 2 है।
