114

141

142

Correct Answer:

114

Explanation:

1   2    3    4   5    6   7     8    9  10  11  12  13

 A   B   C    D   E    F   G    H    I    J    K    L   M

 ↓    ↓    ↓    ↓    ↓     ↓   ↓    ↓     ↓   ↓    ↓    ↓    ↓

 Z   Y    X   W   V    U   T    S    R   Q   P    O   N

26  25  24  23  22  21  20  19  18  17  16  15  14

 

The logic;

(sum of positional value of opposite letter - no. of letters in given word)
 
So,
 'ROUBST' is coded as 61
 
R --> I(9)
O --> L(12)
U --> F(6)
B --> Y(25)
S --> H(8)
T --> G(7)
 
So, 9+12+6+25+8+7 -6
=> 61
 
Similarly,
F --> U(21)
O --> L(12)
R --> I(9)
T --> G(7)
U --> F(6)
N --> M(13)
A --> Z(26)
T --> G(7)
E --> V(22)
 
So, 21+12+9+7+6+13+26+7+22 -9
=> 114.
