Question

In the following question, select the related letters from the given alternatives.
BD: WY :: FH : ?

The correct answer is
AC

Analogy Problem Setup

The question presents a letter analogy: BD is related to WY in the same way that FH is related to the missing pair. We need to find this missing pair using logical reasoning.

Alphabetical Position Mapping

First, assign numerical values to each letter based on its position in the alphabet (A=1, B=2, ..., Z=26):

  • B = 2
  • D = 4
  • W = 23
  • Y = 25
  • F = 6
  • H = 8

Identifying the Transformation Rule

Analyze the transformation from the first pair (BD) to the second pair (WY) to find the pattern:

  • First letter: B (position 2) transforms into W (position 23). The shift is calculated as $23 - 2 = 21$.
  • Second letter: D (position 4) transforms into Y (position 25). The shift is calculated as $25 - 4 = 21$.

The consistent pattern is adding 21 to the position of each letter. If the sum exceeds 26, we wrap around the alphabet (e.g., using the modulo operator).

Applying the Rule to Find the Missing Pair

Now, apply the identified "+21 shift" rule to the letters FH:

First letter (F): Its position is 6.

  • Calculation: $6 + 21 = 27$.
  • Wrap around: The alphabet has 26 letters. $27 \pmod{26} = 1$. The 1st letter of the alphabet is A.

Second letter (H): Its position is 8.

  • Calculation: $8 + 21 = 29$.
  • Wrap around: $29 \pmod{26} = 3$. The 3rd letter of the alphabet is C.

Combining the resulting letters gives the pair AC.

Thus, the completed analogy is BD : WY :: FH : AC.
