Question

If DOOR is coded as EPPQ, then how is FISH coded?

• A. GJTG
• B. GJTI
• C. GKTJ
• D. GJUI

Hint:

To decode letter patterns, convert each character to its alphabetical position (A = 1 to Z = 26), apply the transformation, and then revert.

Answer 1

The Correct Option is A

Pattern Analysis for DOOR → EPPQ

Letter	Alphabet Position	Transformation	Coded Letter
D (4)	4	+1	E (5)
O (15)	15	+1	P (16)
O (15)	15	+1	P (16)
R (18)	18	-1	Q (17)

Pattern Identified: 

• First three letters: +1 position
• Last letter: -1 position

Applying Pattern to FISH

Letter	Alphabet Position	Transformation	Coded Letter
F (6)	6	+1	G (7)
I (9)	9	+1	J (10)
S (19)	19	+1	T (20)
H (8)	8	-1	G (7)

Result: FISH → GJTG

Conclusion:
The correct coded form of FISH is GJTG. If this is not among the provided options, there may be a mistake in the options list.
