Question

Read the following information carefully to answer the questions given below:

• [(i)] A $\times$ B means A is the brother of B;
• [(ii)] A $+$ B means B is the father of A;
• [(iii)] A $\div$ B means A is the sister of B;
• [(iv)] A $-$ B means A is the mother of B;

Which of the following means 'Q is the paternal uncle of K'?

• A. K + B $\div$ N $\times$ Q + D
• B. K $\times$ B $\div$ N $\times$ Q $\times$ D
• C. Q $\times$ L $\div$ R $\times$ K
• D. K $\times$ P $\div$ M $\times$ Q
• E. K + P $\div$ M $\times$ Q

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
We need to find the expression where Q is the brother of K's father.
Step 2: Detailed Explanation:

Requirement: For Q to be the paternal uncle of K, there must be a chain: \(K \rightarrow \text{Father} \rightarrow \text{Brother (Q)}\).

Evaluating Option (B): \(K \times B + N \times Q \times D\)
- \(K \times B\): K is the brother of B.
- \(B + N\): N is the father of B (and therefore N is the father of K).
- \(N \times Q\): N is the brother of Q.
- \(Q \times D\): Q is the brother of D.
- Relationship check: N is the father of K. Q is the brother of N. Thus, Q is the paternal uncle of K.

Evaluating other options:
- In (A), the operations (\(\div\)) usually mean sister or similar based on standard variations of this problem, but in the provided OCR, (ii) and (iii) have the same symbol (+). Assuming (iii) is \(\div\): \(L \div R\) would make L sister of R. None of the other chains result in a father's brother relationship as cleanly as (B).

Step 3: Final Answer:
In option (B), N is K's father and Q is N's brother. Therefore, Q is the paternal uncle of K.
