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.

12 : 1757

The logic is:

(Ist number)³ =  IInd number

11 : 1331  - 11³ = 1331

12 : 1757 - 12³ = 1728 but 1757 is given which is odd

7 : 343    - 7³ = 343

3 : 27     - 3³ = 27
