Question: If \'HELLO\' is coded as \'KHOOR\', what is the code for \'WORLD\'?

Options:

Correct Answer: YQTNF

Solution:

Each letter is shifted by +3. W=23 becomes Z=26, O=15 becomes R=18, R=18 becomes U=21, L=12 becomes O=15, D=4 becomes G=7. Thus, WORLD = YQTNF.

If 'HELLO' is coded as 'KHOOR', what is the code for 'WORLD'?

Step 1: Identify the coding pattern used in the example. Each letter in 'HELLO' is shifted by +3 positions in the alphabet.
Step 2: Write down the letters of the word 'WORLD': W, O, R, L, D.
Step 3: Find the position of each letter in the alphabet: W=23, O=15, R=18, L=12, D=4.
Step 4: Shift each letter by +3 positions: W (23) becomes Z (26), O (15) becomes R (18), R (18) becomes U (21), L (12) becomes O (15), D (4) becomes G (7).
Step 5: Write down the new letters after shifting: Z, R, U, O, G.
Step 6: Combine the new letters to form the coded word: ZRUOG.
