‘A + B’ means ‘A is the brother of B’.
‘A – B’ means ‘A is the mother of B’.
‘A × B’ means ‘A is the father of B’.
‘A ÷ B’ means ‘A is the sister of B’.
If C × M ÷ S × K – T + Q, then which of the following statements is NOT correct?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. M is T's father's sister.
If C × M ÷ S × K – T + Q → C is the father of M, M is the sister of S, S is the father of K, K is the mother of T and T is the brother of Q.

Thus, statement 1 "M is T's father's sister" is NOT correct.
