If in coded language SAURAV = SSUVSR KRITIKA = TTRKRTK ROHINI = IHOHOH Then RAKSHIT = ?

In SAURAV,the first alphabet S comes at number 19 in the english alphabetical list.So start visiting each alphabets of SAURAV starting from first alphabet.In the first visit,S=1 and V=6.In the second visit,S=7 and V=12.Likewise,in the fourth visit,we get S=19.
Now A comes at number 1 in the alphabetical list.So,in the first visit of SAURAV we get S at the first place(S = 1)
Similarly,U comes at number 21.So in the fourth visit of SAURAV,we find that U exists at 21st place too.(U = 21)
R=18 and we get V=18(in 3rd visit)
A=1 and we get S=1 (in 1st visit)
V=22 and we get R=22(in 4th visit)
SAURAV = SSUVSR

The same logic is used in
KRITIKA = TTRKRTK
and
ROHINI = IHOHOH

Applying the same logic in RAKSHIT,
R = 18(in english alphabetical list),and we get S = 18 (in 3rd visit of the word RAKSHIT)
A = 1,and we get R = 1(in 1st visit)
K = 11,and we get S = 11(in 2nd visit)
S = 19,and we get H = 19(in 3rd visit)
H = 8,and we get R = 8(in 2nd visit)
I = 9,and we get A = 9(in 2nd visit)
T = 20,and we get I = 20(in 3rd visit)
RAKSHIT = SRSHRAI

The position of letters of word
SAURAV in English alphabet are
19, 1, 21, 18, 1, 22 respectively.
On writing the word SAURAV in
a running sequence we get
SAURAVSAURAVSAURAVSAURAV.......
19th, 1st, 21st, 18th, 1st and
22nd letters in this sequence
are S, S, U, V, S, R
Similarly for others

option (8)

Let A=1, B=2, C=3, ... z=26.

SAURAV = 19 1 21 18 1 22
Count respective positions in the word. That is first position is S,
second position is A and so on. When you reach last letter in the word, simply resume counting from front.
For a letter in the original word,
find letter corresponding to its number associated in the counting sequence. Replace this all occurrences of the old one
with new, and continue... Then SAURAV=SSUVSR.

Similarly,
KRITIKA=TTRKRTK.
ROHINI=IHOHOH.

Finally, we get

RAKSHIT=SRSHRAI

Let A=1, B=2, C=3, ... z=26.

SAURAV = 19 1 21 18 1 22
Count respective positions in the word. That is first position is S,
second position is A and so on. When you reach last letter in the word, simply resume counting from front.
For a letter in the original word,
find letter corresponding to its number associated in the counting sequence. Replace this all occurrences of the old one
with new, and continue... Then SAURAV=SSUVSR.

Similarly,
KRITIKA=TTRKRTK.
ROHINI=IHOHOH.

Finally, we get

RAKSHIT=SRSHRAI
