Download Solution PDFएक दुकानदार ने 3,600 रुपये में निश्चित संख्या में सेब खरीदे। उसने उनका पांचवां हिस्सा 10% की हानि पर, शेष एक-चौथाई सेब 5% की हानि पर और शेष दो-तिहाई सेब 15% के लाभ पर बेच दिए। कुल मिलाकर 27% का लाभ कमाने के लिए उसे शेष सेब किस कीमत पर (रुपये में) बेचने चाहिए?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिया गया है:
क्रय मूल्य (C.P) = 3600 रुपये
सेब पर कुल लाभ = 27%
प्रयुक्त संकल्पना:
यदि लाभ P% हुआ तो
विक्रय मूल्य (S.P) = C.P × (100 + P)%
जहां, P = लाभ%
गणना:
माना एक सेब की कीमत = 1 रुपये
सेब की मात्रा = 3600
प्रश्न के अनुसार:
⇒ 3600 × (1/5) × (- 10%) + 2880 × (1/4) × (- 5%) + 2160 × (2/3) × 15% + 720 × (x%) = 3600 × 27%
⇒ - 7200 - 3600 + 21600 + 720x = 3600 × 27
⇒ - 720 - 360 + 2160 + 72x = 360 × 27
⇒ 72 × (- 10 - 5 + 30 + x) = 360 × 27
⇒ 15 + x = 5 × 27
⇒ x = 135 - 15 = 120%
शेष सेब का विक्रय मूल्य = 720 × (100 + 120)%
⇒ 720 × 220% = 1584 रुपये
∴ सही उत्तर 1584 रुपये है।
