Question

Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete?
LOK 13, MON 12, NOQ 11, OOT 10, ?

A.

POW 9

B.

IOW 6

C.

POA 9

D.

IOW 7

Correct option is A

Given: LOK 13, MON 12, NOQ 11, OOT 10, ?
Logic: 1st letter + 1, 2nd letter is same, 3rd letter + 3 and number - 1 place.
For, 1st letter
L + 1 = M, M + 1 = N, N + 1 = O, O + 1 = P
Ois same in the middle.
For, 3rd letter
K + 3 = N, N + 3 = Q, Q + 3 = T, T + 3 = W
For, number
13 - 1 = 12, 12 - 1 = 11, 11 - 1 = 10, 10 - 1 = 9
So, the missing term is POW 9.
Thus, correct option is (a).
