The question requires identifying a consistent pattern between the initial pair (XD 15 to BG 20) and the second pair (MT 25 to QW 30) and applying it to find the relation for LR 10.
Let's analyze the change in letters based on their alphabetical position (A=1, B=2, ..., Z=26):
Now, let's analyze the change in numbers:
Apply the established pattern (First letter +4, Second letter +3, Number +5) to LR 10:
Combining these results, LR 10 relates to PU 15.
