Question

If “APPLE” is coded as “BQQMF”, then “MANGO” is coded as:

• A. NBOHP
• B. LZMFO
• C. NCPHQ
• D. ODRIP

Hint:

Always check the first and last letters first. Often, you can eliminate two or three options just by looking at the start of the coded word!

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Coding-Decoding is a common topic in logical reasoning.
The objective is to identify a specific rule or transformation pattern used to convert a set of characters into another set.
In alphabetic coding, the most common patterns involve shifting letters forward or backward in the alphabetical order (A, B, C... Z).
Step 2: Detailed Explanation:
Let's analyze the first pair: "APPLE" and "BQQMF".
We compare each letter of the original word with the corresponding letter of the coded word:
1. A $\rightarrow$ B : A is the 1st letter, B is the 2nd letter. Pattern: +1 shift.
2. P $\rightarrow$ Q : P is the 16th letter, Q is the 17th letter. Pattern: +1 shift.
3. P $\rightarrow$ Q : Again, +1 shift.
4. L $\rightarrow$ M : L is the 12th letter, M is the 13th letter. Pattern: +1 shift.
5. E $\rightarrow$ F : E is the 5th letter, F is the 6th letter. Pattern: +1 shift.
The logic is established: Every letter in the word is shifted forward by one position in the alphabet.

Now, apply this "+1 shift" rule to the word "MANGO":
1. M + 1 = N
2. A + 1 = B
3. N + 1 = O
4. G + 1 = H
5. O + 1 = P
Combining these results, we get the code: NBOHP.
Step 3: Final Answer:
Following the identified pattern of a +1 shift for each letter, the word "MANGO" is coded as NBOHP.
This matches Option (A).
