Q. Which one is different from the rest three ?
a) NMLK
b) WXUV
c) RQPO
d) UTSR
Correct Answer: b) WXUV
Question from UPPSC Prelims CSAT 2025
Explanation:
Options 1, 3, and 4 are four consecutive letters arranged in strict reverse alphabetical order:
– NMLK = reverse of K L M N
– RQPO = reverse of O P Q R
– UTSR = reverse of R S T U
Option 2 (WXUV) is not a single continuous reverse (or forward) sequence. It forms two ascending pairs (W->X and U->V) with a break between X and U. The reverse of U V W X would be X W V U, not W X U V. Hence, Option 2 is different.
