Three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which is the letter-cluster pair that does NOT belong to that group? (Note: The odd one out is not based on the number of consonants/vowels or their positions in the letter-cluster.)
TQ - MJ
ZW - SP
NK - GD
RV - KJ
RV - KJ
Look for the difference between the numerical positions of the letters. In most options, the difference between the two letters in each cluster is 7, while in the odd one, it is not.

Analyze Pattern in Option A
T=20, Q=17 (diff=3); M=13, J=10 (diff=3). Both sub-pairs have a difference of 3.
Analyze Pattern in Option B
Z=26, W=23 (diff=3); S=19, P=16 (diff=3). Both sub-pairs have a difference of 3.
Analyze Pattern in Option C
N=14, K=11 (diff=3); G=7, D=4 (diff=3). Both sub-pairs have a difference of 3.
Analyze Pattern in Option D
R=18, V=22 (diff=+4); K=11, J=10 (diff=1). This does not follow the -3 pattern found in others.
A, B, and C all follow the consistent rule where each letter cluster's constituent letters have a positional difference of 3, whereas D shows inconsistent differences.
D is correct because it is the only option where the positional difference between the letters in the clusters does not follow the constant pattern of 3 observed in the other options.
When faced with letter-cluster analogies, always check the internal positional difference first as it is the most common hidden logic in SSC/Railway exams.
