‘A + B’ means ‘A is the wife of B’
‘A – B’ means ‘A is the husband of B’
‘A × B’ means ‘A is the brother of B’
‘A ÷ B’ means ‘A is the mother of B’
If R + T × S – P ÷ Q + N, then which of the following statements is NOT correct?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Q is the mother of T.
In the diagram shown;
Square shows males, the circle shows females, vertical lines show generations, a single horizontal line shows brothers or sisters, and double lines show a couple.

From the above tree, Q is not the mother of T.
Hence, option 1 is the correct answer.
