If 'A + B' means that A is the brother of B, 'A ÷ B' means that A is the father of B and 'A × B' means that A is the sister of B. Which of the following means 'M' is the uncle of 'P'?


M ÷ N × P.

  2. K ÷ T means K is the father of T. Hence, from information (i), K is also the father of P.
  3. M + K means M is the brother of K. Therefore, using information (ii), we find that M is the uncle of P.
