Given Data

1. Analogy pair given: AZ : BY :: CX : ?

Question

Find the missing letter pair.

Answer

DW.

Solution

1. Observe the pattern across terms:
2. A-Z are opposite complementary letters (1 and 26, sum = 27).
3. B-Y are opposite complementary letters (2 and 25, sum = 27).
4. C-X are opposite complementary letters (3 and 24, sum = 27).
5. The first letters follow the sequence A, B, C, D (4th letter).
6. The opposite complementary letter for D (4) is W (23, since 4 + 23 = 27).
7. Therefore, the missing pair is DW.
