In the following, four roll numbers or centre codes are given. Three share a common pattern or belong to one group, but one is different. Select the odd one out.
440311, 441214, 440598, 681210
Show answer & explanation
Correct answer: D
Explanation
Three of them start with '44', while one starts with '68’.
Since 681210 does not share the same starting digits as the other three, it is the odd one out.
The correct answer is option 4.
