एक दुकानदार एक वस्तु को 10% और 20% की क्रमिक छूट पर बेचने पर 44% का कुल लाभ कमाता है।
प्रयुक्त अवधारणा:
1. विक्रय मूल्य = अंकित मूल्य × (1 - छूट%)
2. विक्रय मूल्य = क्रय मूल्य × (1 + लाभ%)
गणना:
अंतिम छूट% = \(10 + 20 - \frac {10 × 20}{100}\) = 28%
मान लीजिये कि अंकित और क्रय मूल्य क्रमशः = \(10 + 20 - \frac {10 × 20}{100}\) = 28% हैं।
प्रश्न के अनुसार,
MP(1 - 28%) = CP(1 + 44%)
⇒ 0.72 × MP = 1.44 × CP
⇒ MP = 2CP
यदि, 15% छूट की अनुमति दी जाती है तो विक्रय मूल्य
⇒ MP(1 - 15%)
⇒ 0.85MP
⇒ 0.85 × 2CP = 1.7CP
अब, लाभ% = \(\frac {1.7CP - CP}{CP} \times 100\%\) = 70%
∴ कुल लाभ 70% है।
Shortcut Trick
अंतिम छूट% = \(10 + 20 - \frac {10 × 20}{100}\) = 28%
तो, MP : SP = 100 : 72
यहाँ, दुकानदार 44% का कुल लाभ कमाता है
तो, CP : SP = 100 : 144
अब, CP : SP : MP = 100 : 144 : 200
अब, 15% छूट दी गई तो SP = 200 × 85/100 = 170
तो, लाभ% 70/100 × 100 = 70%
