Question

In a certain coding system, 'rbm std bro pus' means "the puppy is beautiful", 'tnh pus dim std' means 'the sparrow is red', 'pus dim bro pus cus' means 'the sparrow has the puppy'. What is the code for 'has'?

• A. dim
• B. pus
• C. bro
• D. std
• E. cus

Hint:

If a word appears in only one sentence, its code is likely the unique code that does not appear in other sentences.

Answer 1

Answer: (E)

Concept: Elimination method: Compare sentences to find common words and their corresponding common codes.
Step 1: Compare Sentence 1 and 2. Common words: "the", "is". Common codes: "std", "pus".

Step 2: Compare Sentence 1 and 3. Common words: "the", "puppy". Common codes: "pus", "bro". From Step 1, we know "the" must be "pus" (since it's in all three). Therefore, "is" = "std" and "puppy" = "bro".

Step 3: Analyze Sentence 3. Words: "the" (pus), "sparrow" (dim), "has" (?), "the" (pus), "puppy" (bro). The only remaining code in Sentence 3 is "cus", which must correspond to "has".
