Download Solution PDFखालील संचातील संख्यांप्रमाणेच ज्या संचातील संख्या संबंधित आहेत तो संच निवडा.
(सूचना: संख्यांचे घटक अंकांमध्ये खंडित न करता, संपूर्ण संख्यांवर गणितीय क्रिया केल्या पाहिजेत. उदाहरणार्थ. 13 - 13 वरील गणितीय क्रिया जसे की 13 मध्ये 'गुणाकार करणे इत्यादी. बेरीज/वजाबाकी करणे. 13 1 आणि 3 मध्ये मोडणे. आणि नंतर 1 आणि 3 वर गणिती क्रिया करण्यास परवानगी नाही)

Detailed Solution
Download Solution PDFतर्क : \(\left[\left(\frac{(1st)Numerator \times 4+ 3}{(1st)Denominator \times 4 + 3 }\right)=\left(\frac{(2nd)Numerator }{(2nd)Denominator}\right)\right]\)
दिलेल्याप्रमाणे:
- \(\left[\left(\frac{7}{9}\right),\left(\frac{31}{39}\right)\right]\)
⇒ \(\left[\left(\frac{7 \times 4+ 3}{9 \times 4 + 3 }\right)=\left(\frac{31}{39}\right)\right]\)
⇒ \(\left[\left(\frac{28+ 3}{36 + 3 }\right)=\left(\frac{31}{39}\right)\right]\)
⇒ \(\left[\left(\frac{31}{39 }\right)=\left(\frac{31}{39}\right)\right]\) (डाव्या हाताची बाजू = उजव्या हाताची बाजू)
30 = 30 (डाव्या हाताची बाजू = उजव्या हाताची बाजू)
- \(\left[\left(\frac{3}{5}\right),\left(\frac{15}{23}\right)\right]\)
⇒ \(\left[\left(\frac{3 \times 4+ 3}{5 \times 4 + 3 }\right)=\left(\frac{15}{23}\right)\right]\)
⇒ \(\left[\left(\frac{12+ 3}{20 + 3 }\right)=\left(\frac{15}{23}\right)\right]\)
⇒ \(\left[\left(\frac{15}{23 }\right)=\left(\frac{15}{23}\right)\right]\) (डाव्या हाताची बाजू = उजव्या हाताची बाजू)
तर,
- पर्याय - (1) : \(\left[\left(\frac{11}{13}\right),\left(\frac{47}{55}\right)\right]\)
⇒ \(\left[\left(\frac{11 \times 4+ 3}{13 \times 4 + 3 }\right)=\left(\frac{47}{55}\right)\right]\)
⇒ \(\left[\left(\frac{44+ 3}{52 + 3 }\right)=\left(\frac{47}{55}\right)\right]\)
⇒ \(\left[\left(\frac{47}{55 }\right)=\left(\frac{47}{55}\right)\right]\) (डाव्या हाताची बाजू = उजव्या हाताची बाजू)
- पर्याय - (2) : \(\left[\left(\frac{9}{13}\right),\left(\frac{37}{55}\right)\right]\)
⇒ \(\left[\left(\frac{9 \times 4+ 3}{13 \times 4 + 3 }\right)=\left(\frac{37}{55}\right)\right]\)
⇒ \(\left[\left(\frac{36+ 3}{52 + 3 }\right)=\left(\frac{37}{55}\right)\right]\)
⇒ \(\left[\left(\frac{39}{55 }\right)=\left(\frac{37}{55}\right)\right]\) (डाव्या हाताची बाजू ≠ उजव्या हाताची बाजू)
- पर्याय - (३) : \(\left[\left(\frac{9}{11}\right),\left(\frac{32}{37}\right)\right]\)
⇒ \(\left[\left(\frac{9 \times 4+ 3}{11 \times 4 + 3 }\right)=\left(\frac{32}{37}\right)\right]\)
⇒ \(\left[\left(\frac{36+ 3}{44 + 3 }\right)=\left(\frac{32}{37}\right)\right]\)
⇒ \(\left[\left(\frac{39}{47}\right)=\left(\frac{32}{37}\right)\right]\) (डाव्या हाताची बाजू ≠ उजव्या हाताची बाजू)
- पर्याय - (4) : \(\left[\left(\frac{17}{19}\right),\left(\frac{36}{77}\right)\right]\)
⇒ \(\left[\left(\frac{17 \times 4+ 3}{19 \times 4 + 3 }\right)=\left(\frac{36}{77}\right)\right]\)
⇒ \(\left[\left(\frac{68+ 3}{76 + 3 }\right)=\left(\frac{36}{77}\right)\right]\)
⇒\(\left[\left(\frac{71}{79}\right)=\left(\frac{36}{77}\right)\right]\)
म्हणून, "पर्याय - (1)" हे योग्य उत्तर आहे.
