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.
Answer & explanation
Correct answer: option 3
The logic followed here Is :
Ist number 2 - 4 = second number
35 : 1221 = 352 - 4 = 1221
21 : 437 = 212 - 4 = 437
11 : 118 = 112 - 4 = 117 ≠ 118
33 : 1085 = 332 - 4 = 1085
