*********************************************

THE LOGIC FOLLOWED HERE IS :

(SUM OF POSITIONAL VALUES OF ALL NUMBERS)2 + 1

AS

BED

= 2 + 5 + 4 = 11

= (SUM OF POSITIONAL VALUES OF ALL NUMBERS)2 + 1

= (11)2 + 1

= 121 + 1 = 122

AND

CAB

= 3 + 1 + 2

= 6

=  (SUM OF POSITIONAL VALUES OF ALL NUMBERS)2 + 1

= (6)2 + 1

= 36  + 1 = 37

SIMILARLY

ADD

= 1 + 4 + 4 = 9

=  (SUM OF POSITIONAL VALUES OF ALL NUMBERS)2 + 1

= (9)2 + 1

= 81  + 1 = 82A
