NORMS is coded as 10 12 14 10 15 N (14) – 4 = 10 O (15) – 3 = 12 R (18) – 4 = 14 M (13) – 3 = 10 S (19) – 4 = 15 and FERN is coded as 02 02 14 11, F (06) – 4 = 02 E (05) – 3 = 02 R (18) – 4 = 14 N (14) – 3 = 11 then, ROME will be coded as R (18) – 4 = 14 O (15) – 3 = 12 M (13) – 4 = 09 E (05) – 3 = 02 Hence, ROME will be coded as 14 12 09 02.
