In a certain code language, 'ALUMNUS' is written as 'ZOFMMFH' and ‘EMINENT’ is written as ‘VNRNVMG’. How will 'HAPPENS' be written in that language?

Let's analyze the relationship for ALUMNUS → ZOFMMFH:
Each letter is replaced by its opposite letter in the English alphabet (A↔Z,B↔Y,…):

A → Z

L → O

U → F

M → M (Wait, opposite of M is N, but here it is M? Let's check positional values: M=13, so 27−13=14=N. But it is written as M. Let's look closely at the whole word).

Let's re-verify the pairs:

A ↔ Z (Opposite)

L ↔ O (Opposite)

U ↔ F (Opposite)

M ↔ M (Stays same? Or +0)

N ↔ M (Opposite)

U ↔ F (Opposite)

S ↔ H (Opposite)
So the middle letter stays same, while all other letters are replaced by their opposites.

Let's check EMINENT → VNRNVMG:

E → V (Opposite)

M → N (Opposite)

I → R (Opposite)

N → N (Middle letter stays same)

E → V (Opposite)

N → M (Opposite)

T → G (Opposite)

This confirms the pattern: the middle letter (4th letter) remains unchanged, and all other letters are replaced by their corresponding opposite letters.

Applying this to HAPPENS (7 letters):

H → S

A → Z

P → K

P → P (4th letter stays unchanged)

E → V

N → M

S → H

Combining these gives SZKPVMH.
