SSC CGL Model Paper 18

Concept:In alphabet-series odd-letter questions, check the gap between consecutive letters.Explanation:Write the alphabetical positions: $J=10$, $G=7$, $D=4$. Here each letter decreases by $3$: $10-3=7$, $7-3=4$. For $NLI$: $N=14$, $L=12$, $I=9$. The differences are $14-12=2$ and $12-9=3$, so the gap is not constant. For $XUR$: $X=24$, $U=21$, $R=18$; the gap is $3$ each time. For $QNK$: $Q=17$, $N=14$, $K=11$; the gap is $3$ each time. Thus, except $NLI$, every option follows a constant gap of $3$. Answer:Option B: $NLI$ is the odd one out.
