Question

In a certain code language, “TABLE” is written as “UBCMF”. How will “CHAIR” be written in that code?

• A. DIBJS
• B. DIBKT
• C. CHBJS
• D. EJCKT

Hint:

To save time during competitive exams, solve using elimination! Look at the first letter: $\text{C} + 1 = \text{D}$. This immediately eliminates choices (c) and (d). Now look at the final letter: $\text{R} + 1 = \text{S}$. This instantly eliminates choice (b), leaving (a) as the only possible correct answer!

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Letter coding puzzles depend on mapping structural alterations across the standard English alphabet tracking index. By decoding how the letters of an example keyword transform into its ciphertext pair, we identify a uniform offset value ($+1$, $-1$, $+2$, etc.) to apply directly to our target word.

Step 2: Key Formula or Approach:
Examine the letter shifts inside the reference pattern: $$\text{Letter}_{\text{Coded}} = \text{Letter}_{\text{Original}} + n$$ Find the step value $n$, then apply that precise letter shift rule across the target characters.

Step 3: Detailed Explanation:
Let's examine the shift spacing inside the reference word pair TABLE $\rightarrow$ UBCMF: $\text{T} \xrightarrow{+1} \text{U}$ $\text{A} \xrightarrow{+1} \text{B}$ $\text{B} \xrightarrow{+1} \text{C}$ $\text{L} \xrightarrow{+1} \text{M}$ $\text{E} \xrightarrow{+1} \text{F}$ The logical pattern shifts every single character forward by exactly one position in alphabetical order ($+1$ progression). Now, apply this identical $+1$ shift rule to every character in the target word CHAIR: $\text{C} \xrightarrow{+1} \text{D}$ $\text{H} \xrightarrow{+1} \text{I}$ $\text{A} \xrightarrow{+1} \text{B}$ $\text{I} \xrightarrow{+1} \text{J}$ $\text{R} \xrightarrow{+1} \text{S}$ Combining these transformed letters gives the coded word DIBJS. This matches option (a) perfectly.

Step 4: Final Answer:
CHAIR will be written as DIBJS in that code language.
