Explanation:

Alright, let’s break this down.

- The original pair is 248 : 428. Look at what’s happening: 248 rearranged (switch the “2” and “4”) gives you 428. So, the relationship here is that the first two digits are switched.

- Now, check each option:

1. 428 : 824

Switch the first two digits of 428; you get 248, not 824. So, this isn’t the same relationship.

2. 268 : 628

Switch the first two digits of 268; you get 628. That matches exactly!

3. 462 : 264

Switch the first two digits of 462; you get 642, not 264. Doesn’t fit.

4. 284 : 842

Switch the first two digits of 284; you get 824, not 842.

So, the right answer is option 2 — 268 : 628
