Blood Relations (Family Relations)

Blood Relation 


Given:



  • A + B → A is the brother of B

  • A − B → A is the sister of B

  • A × B → A is the mother of B

  • A ÷ B → A is the father of B


Question. P is the maternal uncle (Mama) of Q. Which expression is correct ?


Options: A) Q + R − P  B) Q + R × P  C) P + R × Q  D) P × R + Q


Trick


Mama = Mother’s Brother


So look for: P +  R × Q



  • R × Q → R is Q's mother

  • P + R → P is R's brother


Therefore, P = Q's maternal uncle (Mama).


Ans: C) P + R × Q


Trick: Mama = Mother's brother = P + (R × Q)
