Question

In a certain code language,

'A + B' means 'A is the mother of B',

'A - B' means 'A is the brother of B',

'A × B' means 'A is the wife of B' and

'A ÷ B' means 'A is the father of B'.

Based on the above, how is M related to O if 'K ÷ L × M - N + O'?

• A. Wife's father
• B. Mother's brother
• C. Mother's husband
• D. Daughter's husband

Answer 1

Answer:

B. Mother's brother

Given:

• A + B → A is the mother of B

• A - B → A is the brother of B

• A × B → A is the wife of B

• A ÷ B → A is the father of B

Expression:
K ÷ L × M - N + O

Let’s decode step by step from left to right:

1. K ÷ L → K is the father of L.

2. L × M → L is the wife of M.

   • So, M is the husband of L.

3. M - N → M is the brother of N.

4. N + O → N is the mother of O.

Now connect everything:

• M is the brother of N.

• N is the mother of O.

So, M is the brother of O’s mother.
