For GLOSSORY = 97533562:

• G → 9
• L → 7
• O → 5
• S → 3
• S → 3
• O → 5
• R → 6
• Y → 2

For GEOGRAPHY = 915968402:

• G → 9
• E → 1
• O → 5
• G → 9
• R → 6
• A → 8
• P → 4
• H → 0
• Y → 2

Now, for GEOLOGY:

• G → 9
• E → 1
• O → 5
• L → 7
• O → 5
• G → 9
• Y → 2

Thus, the code for GEOLOGY is:

9157592

Divide the word into two groups of five letters each. The first five letters are in group I and the last five letters are in group II. Now, for its coding the middle letters remain unchanged. While the letters in each group change their position as 1 → 3, 2 → 5, 3 → 4, 4 → 2 and 5 → 1.

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.

we can write the given word COMMUNICATIONS as -
C → 1
O → 2
M → 3
M → 4
U → 5
N → 6
I → 7
C → 8
A → 9
T → 10
I → 11
O → 12
N → 13
S → 14
After rearrangement , The letter N will be the tenth letter counting from right .

According to given question,
L → b , X → a , P → e , Z → s , J → p , Y → r , Q → h , M → i , N → g , B → t
