दिया गया है:

पिछले वर्ष मूल्य (Plast) = ₹55,000

इस वर्ष मूल्य (Pthis) = ₹42,500

प्रयुक्त सूत्र:

प्रतिशत कमी = \(\dfrac{(P_{last} - P_{this})}{P_{last}} \times 100\)

गणना:

प्रतिशत कमी = \(\dfrac{(55000 - 42500)}{55000} \times 100\)

⇒ प्रतिशत कमी = \(\dfrac{12500}{55000} \times 100\)

⇒ प्रतिशत कमी = \(0.2273 \times 100\)

⇒ प्रतिशत कमी = 22.73%

∴ सही उत्तर विकल्प 1 है।
