SSC CGL (Prelims) General: Analogy and Series questions with solutions

Q1. What comes next? AZ, BY, CX, ?

1. DW
2. EV
3. DU
4. FW

Answer: DW

In the series, the first letters go A, B, C, D and the second letters go Z, Y, X, W. So the next term is DW.

Q2. Select the letter cluster from among the given options that can replace the question mark (?) in the following series: DFH, EGI, FHJ, ?

1. GIK
2. GJL
3. GHK
4. HJL

Answer: GIK

In the series, each letter in the cluster advances by one position in the alphabet from term to term: D→E→F→G, F→G→H→I, and H→I→J→K. So the next cluster is GIK.

Q3. Which three-letter combination is different? ADF, BEH, CFI, DGJ, EHK

1. ADF
2. BEH
3. CFI
4. DGJ

Answer: ADF

BEH, CFI, DGJ, and EHK each follow a pattern of letters increasing by 3 positions. ADF does not follow this same step pattern, so it is different.

Q4. What comes next? AC, CE, EG, ?

1. GI
2. FH
3. IK
4. JL

Answer: GI

In the series AC, CE, EG, the first letters go A, C, E, which increase by 2 each time. The second letters go C, E, G, also increasing by 2 each time, so the next pair is GI.

Q5. Choose the letter-cluster that fits the question mark in the series: LMP, NOR, PQT, ?

1. RVU
2. RUV
3. STV
4. RSV

Answer: RSV

In each term, the letters advance by 2 positions: L→N→P→R, M→O→Q→S, and P→R→T→V. So the next cluster is RSV.
