‘A + B’ means ‘A is B’s brother’.

‘A – B’ means ‘A is B’s wife’.

‘A × B’ means ‘A is B’s father’.

‘A ÷ B’ means ‘A is B’s daughter’.

Using operations with the same meaning as given above, which of the following options shows ‘M is the mother of O’?

Correct Option/Answer:
The correct option is M − N × O.

Step-by-step Explanation:

Let us analyze the given coded relations:

• 'A + B' means 'A is B’s brother'.
• 'A – B' means 'A is B’s wife'.
• 'A × B' means 'A is B’s father'.
• 'A ÷ B' means 'A is B’s daughter'.

Now, let us evaluate the expression M − N × O step-by-step:

1. M − N:
According to the given definition ('A – B' means 'A is B’s wife'), M is the wife of N. This establishes that M is female and N is her husband.

2. N × O:
According to the given definition ('A × B' means 'A is B’s father'), N is the father of O.

3. Conclusion:
Since N is the father of O, and M is the wife of N, M must be the mother of O.

Hence, the expression M − N × O correctly represents that M is the mother of O.
