Question

Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete?
OU25, PV34, QW43, RX52, ?

A.

SZ62

B.

SY62

C.

SY61

D.

SZ61

Correct option is C

Given: OU25, PV34, QW43, RX52, ?
Logic: 1st letter + 1, 2nd letter + 1 and Number + 9
For, 1st letter
O + 1 = P, P + 1 = Q, Q + 1 = R, R + 1 = S
For, 2nd letter
U + 1 = V, V + 1 = W, W + 1 = X, X + 1 = Y
For, number
25 + 9 = 34, 34 + 9 = 43, 43 + 9 = 52, 52 + 9 = 61
So, the missing term is SY61.
Thus, correct option is (c).
