OJNL is related to NIMK in a certain way based on the English alphabetical order. In the same way, LGKI is related to KFJH. To which of the following is IDHF related, following the same logic?
HCGE
HCEG
HEGC
HECG
HCGE
Observe the pattern: each letter in the target word is replaced by the immediate preceding letter in the English alphabet (N-1).
Observe the pattern: each letter in the target word is replaced by the immediate preceding letter in the English alphabet (N-1).
Analyze the transformation pattern
Mapping OJNL to NIMK: O(15) → N(14), J(10) → I(9), N(14) → M(13), L(12) → K(11). Each letter shifts back by 1 position (-1).
Verify pattern with second pair
Mapping LGKI to KFJH: L(12) → K(11), G(7) → F(6), K(11) → J(10), I(9) → H(8). The -1 shift is confirmed consistently.
Apply pattern to IDHF
I(9) → H(8), D(4) → C(3), H(8) → G(7), F(6) → E(5). Applying the -1 rule to IDHF yields HCGE.
B: HCEG is incorrect because the third and fourth letters are reversed. C: HEGC is incorrect because the second, third, and fourth letters are shuffled. D: HECG is incorrect because the third and fourth letters are swapped from the required sequence.
A is correct because applying a constant shift of -1 to each character of the sequence IDHF results in H(8), C(3), G(7), E(5), which forms HCGE.
For letter-based analogies, always write the positional numbers (1-26) above the letters to quickly identify arithmetic shifts like +1, -1, or +2, -2.
