SSC CGL (Prelims) Reasoning: Series Completion questions with solutions

Q1. Select the option that represents the letters that, when placed from left to right in the blanks below, will complete the given letter series: LMBA_HOLMBAC_OLM_ACHOL_BACHOL_.

1. CHMBM
2. CMHBM
3. CHBMM
4. CHMMB

Answer: CHBMM

The series is built from a repeating pattern of letter groups. Filling the blanks with the correct sequence restores the same cyclic order across all segments. The only option that matches this pattern is CHBMM.

Q2. Which letter-cluster will replace the question mark (?) to complete the given series? ZVRN, VSPM, RPNL, ?, JJJJ

1. RMLN
2. RNLL
3. RNLK
4. NMLK

Answer: NMLK

Each position in the cluster follows a consistent backward shift. Applying the same positional pattern to the missing term gives NMLK. This also leads naturally to the final term JJJJ.
