Given the following coded relationships:

- ‘P @ Q’ means ‘P is the son of Q’
- ‘P ^ Q’ means ‘P is the father of Q’
- ‘P ÷ Q’ means ‘P is the brother of Q’
- ‘P + Q’ means ‘P is the daughter of Q’
- ‘P - Q’ means ‘P is the mother of Q’
- ‘P = Q’ means ‘P is the sister of Q’
- ‘P % Q’ means ‘P is the husband of Q’

If the expressions ‘Q ÷ O - K + D’ and ‘N ÷ M - Q @ L’ are true, which of the following statements is definitely correct?

Question

Given the following coded relationships:

- ‘P @ Q’ means ‘P is the son of Q’
- ‘P ^ Q’ means ‘P is the father of Q’
- ‘P ÷ Q’ means ‘P is the brother of Q’
- ‘P + Q’ means ‘P is the daughter of Q’
- ‘P - Q’ means ‘P is the mother of Q’
- ‘P = Q’ means ‘P is the sister of Q’
- ‘P % Q’ means ‘P is the husband of Q’

If the expressions ‘Q ÷ O - K + D’ and ‘N ÷ M - Q @ L’ are true, which of the following statements is definitely correct?

Accepted Answer

**Solution:**

1. Decode the first expression: `Q ÷ O - K + D`
   - `Q ÷ O` means Q is the brother of O.
   - `O - K` means O is the mother of K.
   - `K + D` means K is the daughter of D.

From this, we get:
   - Q is brother of O.
   - O is mother of K.
   - K is daughter of D.

2. Decode the second expression: `N ÷ M - Q @ L`
   - `N ÷ M` means N is brother of M.
   - `M - Q` means M is mother of Q.
   - `Q @ L` means Q is son of L.

From this, we get:
   - N is brother of M.
   - M is mother of Q.
   - Q is son of L.

3. Analyze relationships:
   - Since M is mother of Q and Q is son of L, L must be the father or mother of Q's parent. Given the coding, L is likely the husband of M (not directly stated but inferred).
   - Q is brother of O's child K's mother (O).
   - Since Q is brother of O and K is daughter of D, D is likely the spouse of O.

4. Therefore, Q is brother of O, and O is married to D, making Q the brother-in-law of D.

**Answer:** Q is the brother-in-law of D
