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.

33 : 109

The logic followed here Is :

(Ist number) × 3  + 4 = second number

44 : 136 = 44 × 3  + 4 = 136

27 : 85 = 27 × 3  + 4 = 85

33 : 109 = 33 × 3  + 4 = 103 ≠ 109

30 : 94 = 30 × 3  + 4 = 94
