The letters of the English alphabet are coded as follows: kth letter of the alphabet is coded as
(i) (k+17)^th letter when 1 ≤ k ≤ 9
(ii) (k-1)^thletter when 10 ≤ k ≤ 18
(iii) (k-18)^th letter when 19 ≤ k ≤ 26
For decoding reverse process is used. The word that is coded as GAURD is

Answer 1

The logic followed here is: kth letter of the alphabet is coded as:

(i) (k+17)th letter when 1 ≤ k ≤ 9

(ii) (k-1)th letter when 10 ≤ k ≤ 18

(iii) (k-18)th letter when 19 ≤ k ≤ 26

For decoding reverse process is used.

So, the word that is coded as GAURD is:

Letter	G	A	U	R	D
Place value	7	1	21	18	4
Reversing the rules	(7 + 18)	(1 + 18)	(21 - 17)	(18 - 17)	(4 + 18)
Place value after applying rules	25	19	4	1	22
Resultant letter	Y	S	D	A	V

Thus, 'YSDAV' is coded as 'GAURD'.

Hence, "Option 2" is the correct answer.
