एक पुस्तक विक्रेता एक गाइडबुक ₹690 में 8% हानि (Loss) पर बेचता है। उसी पुस्तक पर 15% लाभ (Profit) प्राप्त करने के लिए आवश्यक विक्रय मूल्य (Selling price) ज्ञात करें।
Answer और ExplanationAnswer and explanation
Answer: (D) ₹862.50
8% हानि (Loss) पर SP = CP का 92%
क्रय मूल्य (Cost price) = 6900.92 = 690 × 10092 = ₹750
15% लाभ (Profit) के लिए SP = 750 × 1.15 = ₹862.50
✓
आवश्यक विक्रय मूल्य (Selling price) ₹862.50 है।
At 8% loss, SP = 92% of CP
CP = 6900.92 = 690 × 10092 = ₹750
For 15% profit, SP = 750 × 1.15 = ₹862.50
✓
The required selling price is ₹862.50.
SMART APPROACH
92 units = 690 ⇒ 1 unit = 7.5। 15% लाभ (Profit) के लिए 115 units = 115 × 7.5 = ₹862.50।
92 units = 690 ⇒ 1 unit = 7.5. For 15% profit, 115 units = 115 × 7.5 = ₹862.50.
