If ‘CAKE’ is coded as 20 and ‘FAIL’ is coded as 28 then how ‘FIRST’ shall be coded?

Correct option is B

Given
‘CAKE’ is coded as 20 and ‘FAIL’ is coded as 28
Solution:
Here code are sum of positional values of each letter of the words in alphabetical order as shown:
CAKE
The positional value of C,A,K and E as appearing in alphabetical order are:
C = 3
A = 1
K =11
E = 5
Sum = 3+1+11+5 = 20
Similarly for FAIL
F=6
A=1
I= 9
L=12
Sum = 6+1+9+12 =28
So for FIRST code will be:
F = 6
I = 9
R=18
S=19
T= 20
Sum = 6+9+18+19+20= 72
So the code for ‘FIRST’ is 72
