💡 Analysis & Explanation

Decoding the Expression ▼

Let's break down the given equation '$M + N - O \times P \div Q$' step-by-step from left to right.

Relational Mapping ▼

1. $M + N$: M is the mother of N. 2. $N - O$: N is the brother of O. (This means M is also the mother of O). 3. $O \times P$: O is the wife of P. 4. $P \div Q$: P is the father of Q.

Tracing the Final Link ▼

Since P is the father of Q, and O is the wife of P, O must be the mother of Q. Since M is the mother of O, M is the mother of Q's mother.

Conclusion ▼

Therefore, M is the maternal grandmother, or mother's mother, to Q.
