In a certain code language, ‘MOBILES’ is written as ‘N12Y18O22H’ and ‘VEHICLE’ is written as ‘E22S18X15V’. How will ‘NEUTRON’ be written in the same code language?

Let's analyze the coding pattern for MOBILES → N12Y18O22H:
The letters are alternatively converted to opposite letters or positional numbers/transformed values.

Let's look closely at consonants and vowels:

M (Consonant) → N (Opposite letter)

O (Vowel) → 12 (Opposite letter's positional value: O↔L=12)

B (Consonant) → Y (Opposite letter)

I (Vowel) → 18 (Opposite letter's positional value: I↔R=18)

L (Consonant) → O (Opposite letter)

E (Vowel) → 22 (Opposite letter's positional value: E↔V=22)

S (Consonant) → H (Opposite letter)

Wow, the rule is:

Consonants are replaced by their opposite alphabet letter.

Vowels are replaced by the positional value of their opposite alphabet letter.

Let's cross-verify with VEHICLE → E22S18X15V:

V (Consonant) → E (Opposite)

E (Vowel) → 22 (Opposite is V = 22)

H (Consonant) → S (Opposite)

I (Vowel) → 18 (Opposite is R = 18)

C (Consonant) → X (Opposite)

L (Consonant) → O? Wait, in VEHICLE → E22S18X15V:
Let's count positions:
V → E
E → 22
H → S
I → 18
C → X
L → 15 (Opposite of L is O = 15) -> Ah! Here L is treated with its opposite number 15!
E → V (Opposite letter)

Let's look at the alternate positions instead of vowel/consonant:
Positions in MOBILES (7 letters):

M → N (Opposite Letter)

O → 12 (Opposite Value)

B → Y (Opposite Letter)

I → 18 (Opposite Value)

L → O (Opposite Letter)

E → 22 (Opposite Value)

S → H (Opposite Letter)
This perfectly matches Alternate position logic: Odd positions = Opposite Letter, Even positions = Opposite Number.

Let's verify VEHICLE (7 letters) with this alternate position logic:

V (Odd) → E (Opposite Letter)

E (Even) → 22 (Opposite Value)

H (Odd) → S (Opposite Letter)

I (Even) → 18 (Opposite Value)

C (Odd) → X (Opposite Letter)

L (Even) → 15 (Opposite Value)

E (Odd) → V (Opposite Letter)
This perfectly matches the pattern!

Now let's apply this to NEUTRON (7 letters):

N (Odd) → Opposite Letter = M

E (Even) → Opposite Value of E (V) = 22

U (Odd) → Opposite Letter of U = F

T (Even) → Opposite Value of T (G) = 7

R (Odd) → Opposite Letter of R = I

O (Even) → Opposite Value of O (L) = 12

N (Odd) → Opposite Letter of N = M

Combining them, we get: M22F7I12M.
