In a certain code language, ‘RIP’ is written as ‘42’ and ‘MOL’ is written as ‘39’. What will be the code for ‘GAN’ in that code language?

 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 FOLLOWED HERE IS:

ADD THE PLACE VALUE  OF DIGITS - 1

AS

RIP = R + I + P

= 18 + 9 + 16 -1

= 43 - 1 = 42

MOL = M + O + L

= 13 + 15 + 12  - 1

= 40 - 1 = 39

SIMILARLY

GAN  = G + A+ N

=  7 + 1 + 14 - 1

= 22 - 1 = 21

THUS 21 IS CORRECT ANSWER
