Question

If in a certain code, CAT is written as DBU, then DOG will be written as:

• A. EPH
• B. EOG
• C. FPH
• D. EPI

Hint:

In coding-decoding questions, write down the alphabet positions of letters if the shift is larger.
For simple $+1$ or $-1$ shifts, you can directly read the next or previous letters mentally to save time.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
This question belongs to the Coding-Decoding topic of Logical Reasoning.
A word "CAT" is encoded as "DBU" using a specific letter-shifting rule.
We need to decode this rule and apply the exact same transformation to the word "DOG" to find its coded form.

Step 2: Detailed Explanation:
$\bullet$ Let us analyze how the word "CAT" is transformed into "DBU".
$\bullet$ We align the letters of the original word with the coded word:
$\bullet$ C $\rightarrow$ D
$\bullet$ A $\rightarrow$ B
$\bullet$ T $\rightarrow$ U
$\bullet$ Let us look at the alphabetical positions of these letters:
$\bullet$ The letter 'D' is the immediate next letter after 'C' in the English alphabet (a shift of $+1$).
$\bullet$ The letter 'B' is the immediate next letter after 'A' in the English alphabet (a shift of $+1$).
$\bullet$ The letter 'U' is the immediate next letter after 'T' in the English alphabet (a shift of $+1$).
$\bullet$ This reveals that the coding rule is a uniform shift of $+1$ for each letter.
$\bullet$ Now, let us apply this exact $+1$ shifting rule to each letter of the word "DOG":
$\bullet$ First letter: D $+ 1 = $ E
$\bullet$ Second letter: O $+ 1 = $ P
$\bullet$ Third letter: G $+ 1 = $ H
$\bullet$ Combining these letters, we get the coded word: "EPH".

Step 3: Final Answer:
The coded form of the word "DOG" is "EPH".
Therefore, the correct option is (A).
