In a certain code, RAIL is written as KCTN and SPEAK is written as CGR...
To find the code for the word AVOID, we need to understand the pattern used in the given examples of RAIL and SPEAK.
Pattern Analysis:
- Each letter in the word is replaced by a letter that is three places ahead of it in the English alphabet.
- If the letter is near the end of the alphabet, it wraps around to the beginning.
- The position of each letter in the original word remains the same in the coded word.
Using this pattern, let's analyze the coding process for the given examples:
1. RAIL (Original word)
- The first letter R is replaced by the letter three places ahead, which is K.
- The second letter A is replaced by the letter three places ahead, which is C.
- The third letter I is replaced by the letter three places ahead, which is T.
- The fourth letter L is replaced by the letter three places ahead, which is N.
- Therefore, the coded word for RAIL is KCTN.
2. SPEAK (Original word)
- The first letter S is replaced by the letter three places ahead, which is C.
- The second letter P is replaced by the letter three places ahead, which is G.
- The third letter E is replaced by the letter three places ahead, which is R.
- The fourth letter A is replaced by the letter three places ahead, which is U.
- The fifth letter K is replaced by the letter three places ahead, which is M.
- Therefore, the coded word for SPEAK is CGRUM.
Applying the same pattern to the word AVOID:
3. AVOID (Original word)
- The first letter A is replaced by the letter three places ahead, which is D.
- The second letter V is replaced by the letter three places ahead, which is Y.
- The third letter O is replaced by the letter three places ahead, which is R.
- The fourth letter I is replaced by the letter three places ahead, which is L.
- The fifth letter D is replaced by the letter three places ahead, which is G.
- Therefore, the coded word for AVOID is DYRLG.
Therefore, option C - KQXCF is the correct coded form for the word AVOID.
