(A) In this question, the code for the word RAM has been made by adding the positions of all the alphabets in the word and number of letters of the word i.e. R = 18, A = 1, M = 13. So, 18 + 1+ 13 = 32+3. Similarly when the code for the word SHAM would be made it will be S = 19, H = 8, A = 1 and M = 13. Therefore, 19 + 8 + 1 + 13 = 41+4=45.
(B) Now in this case, simply the position of the alphabet is written i.e. R = 18, A = 1, M = 13 and so on. Similarly while making code for the word SUNITA, their alphabetic positions will be written i.e. S = 19, U = 21, N = 14, I = 9 and so on. So the code will become as 1921149201
(C) In this all the letters in word are moved two places forward. So CIVIL will be written as EKXKN.
