Based on the English alphabetical order, three of the following four letter cluster pairs are alike in a certain way and thus form a group. Which pair does NOT belong to that group? (Note: The odd one out is not based on the number of consonants/vowels or their position in the letter cluster)
YD - WD
LN - QS
TV - YA
RT - WY
YD - WD
Look at the letter positions in the English alphabet. Check the difference between the first and second letter of each cluster pair.
Look at the letter positions in the English alphabet. Check the difference between the first and second letter of each cluster pair.
Step 1: Analyze Option B (LN - QS)
L (+2) = N, and Q (+2) = S. Both letter pairs follow a +2 forward shift.
Step 2: Analyze Option C (TV - YA)
T (+2) = V, and Y (+2) = A (wrapping past Z). Both letter pairs follow a +2 forward shift.
Step 3: Analyze Option D (RT - WY)
R (+2) = T, and W (+2) = Y. Both letter pairs follow a +2 forward shift.
Step 4: Analyze Option A (YD - WD)
Y (+5) = D, and W (+7) = D. This does not follow the uniform +2 pattern found in the other three options.
B: LN - QS follows the +2 forward shift in both pairs. C: TV - YA follows the +2 forward shift in both pairs. D: RT - WY follows the +2 forward shift in both pairs.
A is correct because the letter pairs in options B, C, and D all follow a consistent +2 alphabetical forward shift, whereas option A does not follow this uniform rule.
When analyzing letter pairs in reasoning questions, always check standard positional difference before checking vowels, consonants, or opposite pairs.
