Question

If MONDAY is coded as NPOEBZ, how is FRIDAY coded?

• A. GSJEBZ
• B. GQJEBZ
• C. GSJEBX
• D. FSJEBZ

Hint:

For letter coding, check the shift or pattern between letters. Often letters are shifted by a fixed number in the alphabet.

Answer 1

The Correct Option is A

Given the word MONDAY is coded as NPOEBZ. Let's analyze the pattern letter by letter:

\[ \begin{array}{c|cccccc} \text{Letter (Original)} & M & O & N & D & A & Y \\ \hline \text{Letter (Coded)} & N & P & O & E & B & Z \\ \end{array} \] Comparing each letter's position in the alphabet (A=1, B=2, ..., Z=26):
\[ \begin{align*} M(13) &\rightarrow N(14): +1 \\ O(15) &\rightarrow P(16): +1 \\ N(14) &\rightarrow O(15): +1 \\ D(4) &\rightarrow E(5): +1 \\ A(1) &\rightarrow B(2): +1 \\ Y(25) &\rightarrow Z(26): +1 \\ \end{align*} \]
Pattern: Each letter is shifted forward by 1 in the alphabet.

Apply the same to FRIDAY:

\[ \begin{array}{c|cccccc} \text{Letter (Original)} & F & R & I & D & A & Y \\ \hline \text{Letter (Coded)} & G & S & J & E & B & Z \\ \end{array} \] Answer: GSJEBZ
