Find the odd man out:
385, 462, 572, 396, 427, 671, 264

One Answer on this Question

1. 427 is the answer
   Because
   385 means (3+5=8) or (8-3=5) ,
   462 means (4+2=6) or (6-2=4) ,
   572 means (5+2=7) or (7-5=2) ,
   396 means (6+3=9) or (9-3=6) ,
   671 means (6+1=7) or (7-6=1) ,
   264 means (4+2=6) or (6-2=4) ,
   but only 427 is the number in which if we do addition of any of its two digits (e.g 4+2 or 4+7) then its answer doesn’t come 3rd digit
   like if we do 4+2 then answer will be 6 so the number should be 426 but it is not
   or if we do 7-4 then answer will be 3 (not 2)
   so the right answer is 427
