Question

In a certain code, ``MANGO" is written as ``NBOHP". How is "APPLE" written in that code?

• A. BQQMF
• B. BQQLE
• C. AQPMF
• D. BPRLE

Hint:

For coding-decoding problems, compare the original and coded words letter by letter to identify the pattern (e.g., shift in alphabet, reversal). Apply the pattern to each letter of the new word systematically. Check for consistent rules (e.g., +1 to each letter) and verify by testing the coded word against the options.

Answer 1

The Correct Option is A

To decipher the encoding of "MANGO" to "NBOHP" and apply it to "APPLE", we first establish the encoding rule.

1. Foundational Principles:

- Alphabetical Indexing: Assign numerical values to letters (A=1, B=2, ..., Z=26).
- Decoding the Pattern: Determine the positional shift from each letter in "MANGO" to its corresponding letter in "NBOHP".
- Applying the Rule: Utilize the identified shift to encode "APPLE".

2. Analyzing the Transformation:

Original: M(13) A(1) N(14) G(7) O(15)
Encoded: N(14) B(2) O(15) H(8) P(16)

A consistent shift of +1 is observed for each letter.

3. Encoding "APPLE":

A(1) +1 = B(2)
P(16) +1 = Q(17)
P(16) +1 = Q(17)
L(12) +1 = M(13)
E(5) +1 = F(6)

Conclusion:

Under the established code, "APPLE" is encoded as BQQMF.
