If ????? is coded as 'ARGUE' and ????? is SOLVE, What is ??????? is?

Coding of letters is based on the structure of the word. Logic of coding is very simple. Observe the word and the codes. It gives us following information:
If the word consists of four letters,
(i) and consonants occupy places at extreme ends only, then those consonants are replaced by [5] while vowels are replaced by either [20] (if both the vowels are same) or [15] (if both the vowels are different).
(ii) and the vowels occupy the second and the fourth places only then those vowels are replaced by [25], while the consonants are replaced by [5].
(iii) and the vowels occupy the first and third places only then those vowels are replaced by [30], while the consonants are replaced by [5].
If the word consists of three letters,
(i) and the vowels occupy places at extreme ends only then those vowels are replaced by [0], while the consonant is replaced by [5].
(ii) and the consonants occupy places at extreme ends only then those consonants are replaced by [5], while the vowel is replaced by [10].
Thus, in each and every case consonants are coded as [5] but numeric value assigned to vowels varies according to the position of vowels in a particular word.
