Which of the following represents the permutation of 'VTS'?
TVS
VST
TSV
VTS
VST
Look at the pattern of the first, second, and third letters separately: the first letters increase by 3 (H, K, N, Q, T), second letters increase by 3 (J, M, P, S, V), and third letters increase by 3 (G, J, M, P, S).
Look at the pattern of the first, second, and third letters separately: the first letters increase by 3 (H, K, N, Q, T), second letters increase by 3 (J, M, P, S, V), and third letters increase by 3 (G, J, M, P, S).
Analyze 1st Letters
H(8), K(11), N(14), Q(17). The pattern is +3. Next: 17 + 3 = 20, which is T.
Analyze 2nd Letters
J(10), M(13), P(16), S(19). The pattern is +3. Next: 19 + 3 = 22, which is V.
Analyze 3rd Letters
G(7), J(10), M(13), P(16). The pattern is +3. Next: 16 + 3 = 19, which is S.
A: VTS is wrong because the 2nd and 3rd letters are swapped. C: VST is wrong as the letter order does not follow the +3 increment pattern for each slot. D: TSV is wrong as it places T, S, V in an order that violates the established +3 logic for each position.
B is correct because the series follows a consistent +3 alphabetical increment for each of the three letter positions: (H+3=K, J+3=M, G+3=J) → (K+3=N, M+3=P, J+3=M) → (N+3=Q, P+3=S, M+3=P) → (Q+3=T, S+3=V, P+3=S), resulting in TVS.
Always break down multi-letter series into individual positions (1st, 2nd, 3rd) and analyze them separately to avoid confusion.
