Where,
X = alphabetic order of the 1* letter of your sur/last name
Y = alphabetic order of the 2nd letter of your sur/last name
Z = alphabetic order of the 3rd letter of your sur/last name
N=((X+1) % (Z+1))+1 [% indicates modulus operator, example: (5%2)=1, (2%7)=2].
If the value of N>=6, then consider N = 5.
N.B.: Make sure you write down your sure/last name at first and also the values of X, Y,
Z and N. Then, write down the revised table according to those values. Finally, perform
CPM analysis based on the revised table.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa5f58988-40ef-44fb-a7db-3341ff15930d%2F47a3f440-bee8-4995-bcfd-d616fef9d601%2Fq5hsiqt_processed.png&w=3840&q=75)
