Explanation:

Let's break down each operation as per the given notations:

- A * B: A is the father of B

- A ­ B: A is the sister of B

- A + B: A is the mother of B

- A ÷ B: A is the brother of B

Now, let's solve the expression: P + Q * M ÷ N

1. P + Q: P is the mother of Q

2. Q * M: Q is the father of M

3. M ÷ N: M is the brother of N

So, combine them step by step.

- Q is the father of M, and P is the mother of Q.

- That means P is M's grandmother (on the father's side).

- M is also the brother of N, showing M is male.

Now, the question is: How is M related to P?

M is P's grandson.

- Option 1: Granddaughter

- Option 2: Grandson

- Option 3: Daughter

- Option 4: Son

Correct Answer:

Option:2, Grandson
