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 from the rest.
Answer & explanation
Correct answer: option 4
The logic followed here is:
(Ist number × 7) + 7 = Second number
37 : 266 = (37 × 7) + 7 = 266
53 : 378 = (53 × 7) + 7 = 378
45 : 322 = (45 × 7) + 7 = 322
43 : 318 = (43 × 7) + 7 = 308 ≠ 318
