Which Word Should Be In Place of ? In The Following  XVWU : TRSQ = LJKI : ?

Each letter in XVWU is shifted back by 4 places to give TRSQ: X(24) to T(20), V(22) to R(18), W(23) to S(19), U(21) to Q(17). Apply the same backward shift of 4 to LJKI: L(12) to H(8), J(10) to F(6), K(11) to G(7), I(9) to E(5). That gives HFGE, which is option A.

• A) HFGE is correct. It follows the uniform -4 shift in every position.
• B) EFGH is wrong. It is just the alphabetical run of four letters, and E is 7 places from L, not 4.
• C) FGHE is wrong. Its first letter F is 6 places from L, so the shift breaks at once.
• D) GHEF is wrong. It uses rearranged letters, but G is 5 places from L, not 4.

Core concept: a uniform letter-shift code, which is a pattern-recognition item under reasoning and logical ability. The same skill helps with coding-decoding and series questions in Mains General Studies II and the essay-style reasoning that examiners reward.

Trap: aspirants check only the first letter, or see that the options use the same letters as a rearrangement, and pick a rotation like GHEF. Always verify all four positions with the same shift.
