Detailed Solution
Download Solution PDFगणना:
10R + 4M = 210000 … (i)
6R + 2M = 122000… (ii)
समीकरण (ii) को 2 से गुणा करने और समीकरणों को घटाने पर, हमें प्राप्त होता है
10R + 4M = 210000
12R + 4M = 244000
- 2R = - 34000
⇒ R = 34000/2 = 17000
अब, मान को समीकरण (ii) में रखें, हमें प्राप्त होता है
6 × 17000 + 2M = 122000
⇒ 2M = (122000 - 102000)
⇒ M = 10000
इसलिए, एक रेफ्रिजरेटर और दो मोबाइल फोन की कीमत = (17000 + 2 × 10000) = 37000
∴ सही उत्तर 37000 है।
