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:
Ist number × 6 - 5 = second number
28 : 163 → 28 × 6 - 5 = 163
16 : 91 → 16 × 6 - 5 = 91
27 : 82 → 27 × 6 - 5 = 157 ≠ 82
22 : 127 → 22 × 6 - 5 = 127
