Select the pair that follows the same pattern as that followed by the two pairs given
below. Both pairs follow the same pattern.
NHF : MDB
QKF : PGB
- A.
INS : HKP
- B.
TED : SAA
- C.
ORL : NOH
- D.
JSK : IOG
Show answer & explanation
Correct answer: D
Concept: In a letter-pair analogy, each letter of the first term is shifted by a fixed number of positions in the alphabet to give the corresponding letter of the second term. The shift applied to the 1st, 2nd, and 3rd letters must be identical across the two given pairs and the correct pair.
Application: Find the shift-triple shared by both given pairs:
NHF : MDB — N→M is a shift of −1 (14→13); H→D is a shift of −4 (8→4); F→B is a shift of −4 (6→2).
QKF : PGB — Q→P is a shift of −1 (17→16); K→G is a shift of −4 (11→7); F→B is a shift of −4 (6→2).
Both given pairs share the same shift-triple: (−1, −4, −4) applied to the 1st, 2nd, and 3rd letters respectively.
Cross-check: Apply the shift-triple (−1, −4, −4) to each candidate pair’s first term and compare the result with its second term.
Pair | 1st letter shift | 2nd letter shift | 3rd letter shift |
|---|---|---|---|
INS : HKP | −1 (I→H) | −3 (N→K) | −3 (S→P) |
TED : SAA | −1 (T→S) | −4 (E→A) | −3 (D→A) |
ORL : NOH | −1 (O→N) | −3 (R→O) | −4 (L→H) |
JSK : IOG | −1 (J→I) | −4 (S→O) | −4 (K→G) |
Only JSK : IOG reproduces the (−1, −4, −4) shift-triple established by both given pairs, so JSK : IOG is the pair that follows the same pattern.
