Based on the English alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which letter-cluster does not belong to that group?
(Note: The odd letter-cluster is not based on the number of consonants/vowels or their position in the letter-cluster.)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. SPU.
Option 1: PMS ⇒P - 3 = M, M + 6 = S
Option 2: URX ⇒ U - 3 = R, R + 6 = X
Option 3: JGM ⇒ J - 3 = G, G + 6 = M
Option 4: SPU ⇒ S - 3 = P, P + 6 = V ≠ U
All are follow the same logic except option 4.
