OFNPEZ
โœ“ Correct
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
The coding pattern follows an alternating sequence where each letter shifts forward in the alphabet by +2, then +1, +2, +1, and so on.

Let's break down the pattern using STRIKE โ†’ UUTJMF:
S (+2) โ†’ U
T (+1) โ†’ U
R (+2) โ†’ T
I (+1) โ†’ J
K (+2) โ†’ M
E (+1) โ†’ F

Applying the Pattern to MELODY

Using the exact same alternating +2, +1 rule:

M (+2) โ†’ O
E (+1) โ†’ F
L (+2) โ†’ N
O (+1) โ†’ P
D (+2) โ†’ E
Y (+1) โ†’ Z

This results in the code OFNPEZ.

Coding and Decoding Test: In this type of questions, words are not written directly. They are written in code words. The letters do not represent themselves but they represent some other alphabets. Thus these letters acquire some artificial value. The value to these letters is not allotted in haphazard way, rather a set pattern is followed. For tackling these questions the examinee should first sense out the pattern or relationship followed by the letters given in the first set of code word and clear word. He should apply the same rule in decoding the other coded word.
