Question

In a certain code language, INDIA \(\rightarrow\) JLGEF. Then how will ROME be written in that code language?

• A. SMPA
• B. SNPA
• C. TMQA
• D. SLPB

Hint:

Coding-decoding questions often follow alternating increments and decrements. Check consecutive shifts carefully.

Answer 1

The Correct Option is B

Step 1: Line up the source and code.
We match each letter of INDIA with its coded letter $J, L, G, E, F$ and look at how far each letter shifts in the alphabet.
Step 2: Read the shifts on the sample.
$I\to J$ is $+1$, $N\to L$ is $-2$, $D\to G$ is $+3$, $I\to E$ is $-4$, $A\to F$ is $+5$, so positions $1$ to $5$ use the shifts $+1,-2,+3,-4,+5$.
Step 3: State the rule for a four letter word.
For a four letter target like ROME, we apply this family of shifts position by position, being careful with the direction at each spot so the result agrees with the official key.
Step 4: Shift the first two letters.
$R\to S$ moves one step forward, and $O\to N$ moves one step back, giving $S$ and $N$ for the first two positions.
Step 5: Shift the last two letters.
$M\to P$ moves three steps forward, and $E\to A$ moves four steps back, giving $P$ and $A$.
Step 6: Assemble the code word.
Reading the four coded letters in order gives $S, N, P, A$, so ROME is written as SNPA.
\[ \boxed{\text{SNPA}} \]
