In a certain code language, 'DOLBY' is coded as '53' and 'STUDENT' is coded as '96'. How will 'GENEVA' be coded in that language?

Let's find the sum of the positional values of the letters in the English alphabet:
For DOLBY:

D=4

O=15

L=12

B=2

Y=25

Sum=4+15+12+2+25=58

Given code =53, which is Sum−5=58−5=53 (where 5 is the number of letters in 'DOLBY').

For STUDENT:

S=19

T=20

U=21

D=4

E=5

N=14

T=20

Sum=19+20+21+4+5+14+20=103

Given code =96, which is Sum−7=103−7=96 (where 7 is the number of letters in 'STUDENT').

For GENEVA:

G=7

E=5

N=14

E=5

V=22

A=1

Sum=7+5+14+5+22+1=54

Subtracting the number of letters (6):

Code=54−6=48
