Question

If in a certain code, “PENCIL” is written as “QFODJM”, then “BOOK” will be written as: ____.

• A. CPLL
• B. CPPM
• C. DQQM
• D. CQQL

Hint:

Always write out the alphabet or your A=1, B=2 chart quickly during an exam. It prevents simple "off-by-one" errors when counting letters in your head!

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
This is a coding-decoding problem where we need to find the pattern between the original word and its code and apply it to the target word.
Step 2: Detailed Explanation:
First, let's identify the pattern in "PENCIL" \(\rightarrow\) "QFODJM":
P (+1) \(\rightarrow\) Q
E (+1) \(\rightarrow\) F
N (+1) \(\rightarrow\) O
C (+1) \(\rightarrow\) D
I (+1) \(\rightarrow\) J
L (+1) \(\rightarrow\) M
The pattern is simply adding +1 to each letter (moving to the next letter in the alphabet).
Now, apply this pattern to "BOOK":
B (+1) \(\rightarrow\) C
O (+1) \(\rightarrow\) P
O (+1) \(\rightarrow\) P
K (+1) \(\rightarrow\) L
The result is "CPPL".
Looking at the options provided in the PDF key/OCR: (A) CPLL, (B) CPPM. There might be a slight typo in the options or code generation, but following the consistent +1 shift of the first three letters and mapping to the closest option (A) CPLL or (B) CPPM depending on common exam errata. Usually, K+1=L, making CPPL the standard result. Based on the OCR (A) CPLL is the closest alphabetical match.
Step 3: Final Answer:
Following the +1 logic, the most appropriate choice from the set provided is CPLL.
