Question

Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete?
NQ27, MP38, LO49, KN60,  ?

A.

JM71

B.

JN72

C.

JM72

D.

JN71

Correct option is A

Given series:
NQ27 → MP38 → LO49 → KN60 → ?
Logic: letter -1 and number +11
First letter pattern
N → M → L → K → ?
N (14) - 1 = M (13)
M (13) - 1 = L (12)
L (12) - 1 = K (11)
K (11) - 1 = J (10)
Second letter pattern
Q → P → O → N → ?
Q (17) - 1 = P (16)
P (16) - 1 = O (15)
O (15) - 1 = N (14)
N (14) - 1 = M (13)
Number pattern
27 → 38 → 49 → 60 → ?
38 - 27 = 11
49 - 38 = 11
60 - 49 = 11
Next number: 60 + 11 = 71
Correct answer is (a) JM71.
