Study the following information carefully and answer the questions given below:

In a certain code language:
“Heavy cargo arrived today” is coded as “xp zm rk wt”
“Arrived ship harbor dock” is coded as “qv wt ny js”
“Ship cargo from ocean” is coded as “qv zm fl ug”
“Many harbor boats today” is coded as “wb hp ny rk”

What is the code for “ocean”?

Correct Answer: Either ug or fl

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

Given Statements:
1. “Heavy cargo arrived today” → “xp zm rk wt”
2. “Arrived ship harbor dock” → “qv wt ny js”
3. “Ship cargo from ocean” → “qv zm fl ug”
4. “Many harbor boats today” → “wb hp ny rk”

Step-by-step Decoding:

1. Code for “cargo”:
Comparing Statement 1 and Statement 3, the common word is “cargo”, and the common code is “zm”.

$\text{cargo}=\text{zm}$

2. Code for “arrived”:
Comparing Statement 1 and Statement 2, the common word is “arrived”, and the common code is “wt”.

$\text{arrived}=\text{wt}$

3. Code for “today”:
Comparing Statement 1 and Statement 4, the common word is “today”, and the common code is “rk”.

$\text{today}=\text{rk}$

4. Code for “ship”:
Comparing Statement 2 and Statement 3, the common word is “ship”, and the common code is “qv”.

$\text{ship}=\text{qv}$

5. Finding code for “ocean”:
Look closely at Statement 3: “Ship cargo from ocean” is coded as “qv zm fl ug”.
We already know:
- “ship” = “qv”
- “cargo” = “zm”

Eliminating these from Statement 3 leaves us with the words “from ocean” and the codes “fl ug”.
Since there are no other statements containing the words “from” or “ocean”, we cannot uniquely determine which code corresponds to which word.

Therefore, the code for “ocean” must be either ug or fl.
