But also 28 is a possible choice. Or the other way around we do have a possible arrangement.

D is the answer.

Hope this helps.

what would be the best way to solve this problem? This would be a question that I would probably skip because I would have to just try different combinations and would sink a lot of time. Perhaps its just about number sense?

Since the digits differ by 6, the only possible combos that will work are 3,9, 2,8, 1,7, and 0,6. So only 4 to plug-and-check.
