The second letter-group is related to the first letter-group following a specific logical pattern. Based on this same pattern, which of the following letter-groups replaces the question mark?

FLUID:XRIUZ::SMART:?\text{FLUID} : \text{XRIUZ} :: \text{SMART} : \text{?}

  1. KQCLJAnswer
  2. B
    HNZIG
  3. C
    VPDUW
  4. D
    EKWFD

Answer

KQCLJ
The correct answer is derived by first replacing each letter in the word 'SMART' with its reverse alphabetical pair (S becomes H, M becomes N, A becomes Z, R becomes I, T becomes G), and then shifting each resulting letter forward by 3 positions in the alphabet to yield 'KQCLJ'.

Step-by-Step Solution

1
Analyze the relationship between the first pair of letter-groups (FLUID and XRIUZ).
Identify the two-step transformation: finding the reverse alphabetical letter for each character, then shifting forward by 3 positions.
Establishing the exact dual-rule pattern in the complete pair is necessary to reliably apply it to the target word.
2
Apply the first step (reverse alphabetical position) to the word SMART.
S becomes H, M becomes N, A becomes Z, R becomes I, and T becomes G, resulting in the intermediate string HNZIG.
This completes the mirror pair transformation based on the established sequence of logic.
3
Apply the second step (forward shift of +3) to the intermediate result HNZIG.
H+3 = K, N+3 = Q, Z+3 = C, I+3 = L, G+3 = J. The final letter-group is KQCLJ.
This completes the full transformation rule, providing the final missing analogical term.
