Question
Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the one that is different.

E.g. 13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
