Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the number-pair that is different.
Answer & explanation
Correct answer: option 3
The logic followed here is:
12 : 156 → 122 + 12 =156
18 : 342 → 182 + 12 = 342
17 : 307 → 172 + 17 = 306 ≠ 307(odd)
14 : 210 → 122 + 12 = 210
