Detailed Solution
Download Solution PDFతర్కం ఏమిటంటే:
1వ సంఖ్య × 7 - 8 = రెండవ సంఖ్య
1. 21 ∶ 139 → 21 × 7 - 8 = 147 - 8 = 139
2. 25 : 167 → 25 × 7 - 8 = 175 - 8 = 167
3. 15 : 197 → 15 × 7 - 8 = 105 - 8 = 97 ≠ 197
4. 27 : 181 → 27 × 7 - 8 = 189 - 8 = 181
ఎంపిక 3 తప్ప, అన్ని ఎంపికలు ఇచ్చిన లాజిక్ను అనుసరిస్తాయి. అందువలన ఎంపిక 3 భిన్నమైనది.
కాబట్టి, ' 15 : 197 ' అనేది భిన్నమైనది.
