Q. From the following alternatives find the one that does NOT belong to the rest.
a) DHG
b) JNR
c) CGF
d) HLK
Correct Answer: b) JNR
Question from UPPSC Prelims CSAT 2025
Explanation:
Assign positions A=1, …, Z=26 and check successive differences:
– DHG: 4 to 8 (+4), 8 to 7 (-1)
– JNR: 10 to 14 (+4), 14 to 18 (+4)
– CGF: 3 to 7 (+4), 7 to 6 (-1)
– HLK: 8 to 12 (+4), 12 to 11 (-1)
In three options (DHG, CGF, HLK) the pattern is +4 then -1 (increase then decrease). Only JNR keeps increasing with +4 then +4. Hence JNR (Option 2) does NOT belong.
