AD32 is related to EH16 in a certain way. In the same way, MT40 is related to QX20. Towhich of the following is KN62 related, following the same logic?

AD32 → EH16

MT40 → QX20

​KN62 → ? 

Logic: Letters + 4 = Next letters, Numbers ÷ 2 = Next number.

A + 4 = E
D + 4 = H
32 ÷ 2 = 16

M + 4 = Q
T + 4 = X
40 ÷ 2 = 20
​KN62 → ? 

K + 4 = O
N + 4 = R
62 ÷ 2 = 31
So, KN62 → OR31

Thus, the correct option is  (a) OR31.
