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.
Answer & explanation
Correct answer: option 4
The logic followed here is :
ist number - 118 = IInd number
797 : 679 ⇒ 797 -118 = 679
373 : 255 ⇒ 373 -118 = 255
727 : 609 ⇒ 727 -118 = 609
191 : 177 ⇒ 191 -118 = 73 ≠ 177 (odd)
