Question : Directions: Select the option that represents the letters that, when sequentially placed from left to right in the blanks below, will complete the letter series.
C _ _ SRCNP _ _ _ N _ SRC _ PS _

Option 1: PSNRCPNR

Option 2: NPSRCPRN

Option 3: NPSRPCRN

Option 4: NPSRCPNR

Correct Answer: NPSRCPNR

Solution : Given:
C _ _ SRCNP _ _ _ N _ SRC _ PS _

To fill the series we have to divide the series – C _ _ SR / CNP _ _ / _ N _ SR / C _ PS _

Let's check each option –
First option: PSNRCPNR ; C PS SR / CNP NR / C N P SR / C N PS R (No repeated pattern has been found)
Second option: NPSRCPRN ; C NP SR / CNP SR / C N P SR / C R PS N (No repeated pattern has been found)
Third option: NPSRPCRN ; C NP SR / CNP SR / P N C SR / C R PS N (No repeated pattern has been found)
Fourth option: NPSRCPNR ; C NP SR / CNP SR / C N P SR / C N PS R (CNPSR is repeated in the series)

So, the series becomes→CNPSRCNPSRCNPSRCNPSR. Hence, the fourth option is correct.
