Which of the following letter-clusters will replace the question mark (?) in the given series to make it logically complete?
PSU, GBL, ?, OTT, FCK
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3. i.e. XKC.
Given : PSU, GBL, ?, OTT, FCK
Logic : First letter - 9 , Second letter + 9 , Third letter - 9
⇒P - 9 = G
S + 9 = B
U - 9 = L
⇒ G - 9 = X
B + 9 = K
L - 9 = C
Thus , XKC completes the series.
Hence , XKC is the correct answer.
