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.

7 : 360

The logic followed here is :

Ist number³  + ist number = second number

12 : 1740 -  12³ + 12 = 1740

6 : 222     -   6³ + 6 = 222

11 : 1342 -   11³ + 11 = 1342

7 : 360     -   7³ + 7 = 350 ≠ 360
