In a certain code language, NAMAN is written as 92. How will CARPET be written as in that language?

Given: NAMAN is written as 92

Logic: Sum of opposite letter place values in the English alphabet = Code.

For "NAMAN"
N ↔ M → 13
A ↔ Z →  26
M ↔ N →  14
A ↔ Z → 26
N ↔ M →  13
Total Sum = 13 + 26 + 14 + 26 + 13  = 92 
Applying same logic For "CARPET"
C ↔ X →  24
A ↔ Z → 26
R ↔ I →  9
P ↔ K → 11
E ↔ V → 22
T ↔ G → 7 
Total Sum = 24 + 26 + 9 + 11 + 22 + 7 =  99 
Thus, the correct option is (a) 99​​
