Correct Answer - Option 4 : C
The pattern followed here is:
Take Z = 1, Y = 2, X = 3 .............. A = 26.
According to the given alphabetical positions of the letters,
For STOP :
S → 8
T → 7
O → 12
P → 11
STOP = 8 + 7 + 12 + 11 = 38
Similarly,
POSTMAN :
P → 11
O → 12
S → 8
T → 7
M → 14
A → 26
N → 13
POSTMAN = 11 + 12 + 8 + 7 + 14 + 26 + 13 = 91
Hence, ‘91’ is the correct answer.
