In a certain code language;
“stay calm be ready” is coded as “mn jk lm rs”
“ready for stay quiet” is coded as “rp jk ut mn”
“calm nature for peace” is coded as “lm ve rp st”
“nature quiet for calm” is coded as “ve ut rp lm”

What will be the code for “be”?

The correct option is rs.

To find the code for the word “be”, let us analyze the given statements step-by-step by comparing common words and their corresponding codes:

1. Statement 1: “stay calm be ready” = “mn jk lm rs”
2. Statement 2: “ready for stay quiet” = “rp jk ut mn”
3. Statement 3: “calm nature for peace” = “lm ve rp st”
4. Statement 4: “nature quiet for calm” = “ve ut rp lm”

Step 1: Find the code for “calm”
Comparing Statement 1 and Statement 3, the common word is “calm”.
Comparing their codes (“mn jk lm rs” and “lm ve rp st”), the common code is “lm”.
Therefore, “calm” = “lm”.

Step 2: Find the codes for “stay” and “ready”
Comparing Statement 1 and Statement 2, the common words are “stay” and “ready”.
Comparing their codes, the common codes are “mn” and “jk”.
So, the set of words {“stay”, “ready”} corresponds to the set of codes {“mn”, “jk”}.

Step 3: Determine the code for “be”
In Statement 1, we have four words: “stay”, “calm”, “be”, and “ready”, with codes “mn”, “jk”, “lm”, and “rs”.
From our previous steps:
- “calm” is coded as “lm”
- “stay” and “ready” are coded as “mn” and “jk” (in some order)

The only remaining word in Statement 1 is “be”, and the only remaining code is “rs”.
Hence, the code for “be” is “rs”.
