Download Solution PDFयहाँ अनुसरण किया गया तर्क निम्नलिखित है:
तर्क: (पहली संख्या ÷ 2) + 1 = दूसरी संख्या
प्रत्येक विकल्प की तर्क के अनुसार जाँच करते हैं,
1) 20 ∶ 11 → (20 ÷ 2) + 1 = 10 + 1 = 11
2) 6 ∶ 4 → (6 ÷ 2) + 1 = 3 + 1 = 4
3) 15 ∶ 9 → (15 ÷ 2) + 1 = 7.5 + 1 = 8.5 ≠ 9
4) 12 ∶ 7 → (12 ÷ 2) + 1 = 6 + 1 = 7
यहाँ, हम देख सकते हैं कि केवल विकल्प 3 तर्क का अनुसरण नहीं करता है।
अतः सही उत्तर "15 ∶ 9" है।
