Question

In a certain code language, `EARTH' is written as `JFWYM'. How is `WORLD' written in that code?

• A. BTWNE
• B. BTXNE
• C. BSXNE
• D. BTWQI

Hint:

For coding-decoding, convert letters to alphabetical positions (A=1, ..., Z=26) and check for consistent shifts, accounting for wrap-around (modulo 26).

Answer 1

The Correct Option is D

To solve the problem, we need to find the pattern used to convert the word "EARTH" into "JFWYM" and then apply the same pattern to the word "WORLD".

1. Understanding the Given Example:

- Original word: E A R T H
- Coded word: J F W Y M

2. Finding the Pattern:

Let's find the shift in letters from the original word to the coded word by comparing their positions in the alphabet:

Letter	E	A	R	T	H
Position	5	1	18	20	8
Coded	J	F	W	Y	M
Position	10	6	23	25	13
Shift	+5	+5	+5	+5	+5

Each letter in "EARTH" is shifted forward by 5 positions to get the coded letter.

3. Applying the Pattern to "WORLD":

Find the position of each letter and add 5 (if the position exceeds 26, wrap around by subtracting 26):

Letter	W	O	R	L	D
Position	23	15	18	12	4
Shifted (+5)	28	20	23	17	9
After wrapping	28 - 26 = 2 (B)	20 (T)	23 (W)	17 (Q)	9 (I)

4. Writing the Code for "WORLD":

The coded word is: BTWQI

Final Answer:

"WORLD" is written as "BTWQI" in that code.
