DEF is related to CDE in a certain way. In the same way, MNO is related to LMN. To which of the following options is UVW related, following the same logic?
EFD
FED
TUV
FDE
TUV
Observe that each sequence is a group of three consecutive letters (A, B, C, D...), and the relation is 'previous three-letter sequence'. Simply identify the sequence of three letters that immediately precedes the given set in the English alphabet.
Observe that each sequence is a group of three consecutive letters (A, B, C, D...), and the relation is 'previous three-letter sequence'. Simply identify the sequence of three letters that immediately precedes the given set in the English alphabet.
Analyze the first pattern
DEF consists of letters at positions 4, 5, 6. CDE consists of letters at positions 3, 4, 5. The pattern is subtracting 1 from the position of each letter: D-1=C, E-1=D, F-1=E.
Verify with the second pattern
MNO (13, 14, 15) follows the same rule: M-1=L, N-1=M, O-1=N, resulting in LMN.
Apply logic to the target
For UVW (21, 22, 23), subtracting 1 from each gives: U-1=T, V-1=U, W-1=V. The result is TUV.
A: EFD does not follow the consecutive sequence reduction pattern. B: FED is a reverse permutation, not a reduction. D: FDE is a scrambled set and does not maintain the sequential order.
C is correct because each letter in the sequence UVW (positions 21, 22, 23) is shifted backward by 1 position in the English alphabet, resulting in TUV (20, 21, 22).
When dealing with three-letter sequence problems, always check if the change is a simple shift (e.g., +1 or -1) or a reversal of letters, as these are the two most common patterns in competitive exams.
