If BDCB is related to YWXY, then FGHF is related to:
UTSU
UTVU
USTU
VUTV
UTSU
Identify that the relationship is based on opposite letter pairs where the sum of forward and backward positional values for each letter is always 27.
Identify that the relationship is based on opposite letter pairs where the sum of forward and backward positional values for each letter is always 27.
Analyze the Base Relationship
Examine the correspondence between BDCB and YWXY. Each letter is replaced by its exact reverse alphabet counterpart: B (2) maps to Y (25), D (4) maps to W (23), C (3) maps to X (24), and B (2) maps to Y (25). The sum of positions in each pair equals 27.
Apply the Rule to FGHF
Apply the same reverse alphabet transformation (27 minus position) to each letter of FGHF: F (6) becomes 21st letter U, G (7) becomes 20th letter T, H (8) becomes 19th letter S, and F (6) becomes 21st letter U. This yields UTSU.
B: UTVU is incorrect because the third letter is V instead of S. C: USTU is incorrect because the second letter is S instead of T. D: VUTV is incorrect because the first and fourth letters are V instead of U.
A is correct because applying the opposite letter rule to FGHF yields UTSU.
Memorize the AZ backward mapping or the rule that opposite letters add up to 27 to instantly solve letter coding questions.
