In a certain code language, TIFFIN is coded as 67 and BOX is coded as 44. How will CARDBOARD be coded as in that language?

69

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

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

THE LOGIC FOLLOWED HERE IS:

SUM OF THE PLACE VALUE OF LETTER + 3

TIFFIN  = 20 + 9 + 6 + 6 + 9 + 14 = 64

TIFFIN = 64 + 3 = 67

BOX = 2 + 15 + 24 = 41

BOX =  41  + 3 = 44

SIMILARLY

CARDBOARD = 3 + 1+ 18+ 4 + 2 + 15+ 1 + 18 +4 = 66

CARDBOARD = 66 + 3 = 69
