नीचे चार संख्या-युग्म दिए गए हैं जिनमें से तीन किसी संदर्भ में एक समान हैं और उनमें से एक असंगत है। उस असंगत संख्या-युग्म का चयन करें।
Detailed Solution & Logic
Correct Answer:
(547, 258)
Check the pattern in each pair:
- (547, 258)
$5+4+7 = 16$, and $16^2 = 256 \approx 258$ (not exact, but check others first) - (723, 144)
$7+2+3 = 12$, and $12^2 = 144$ ✔ - (812, 121)
$8+1+2 = 11$, and $11^2 = 121$ ✔ - (546, 225)
$5+4+6 = 15$, and $15^2 = 225$ ✔
Now check the first properly:
$5+4+7 = 16$, and $16^2 = 256 \ne 258$
So only the first pair does not follow the rule.
Answer: (547, 258)
