If A + B means A is the brother of B; \[A\div B\]means A is the father of B and\[A\times B\]means A is the sister of B, then which of the following means M is the uncle of P?
A) \[N\times P\div M\]
B) \[M+S\div R\div P\]
C) \[M\div N\times P\]
D) \[M+K\div T\times P\]
Correct Answer:
D
Solution :
\[\Rightarrow \] P is M's father and N is P's sister, i.e. M is son or daughter of P, not uncle. \[\Rightarrow \] R is P's father and S is R's father, i.e. S is grandfather of P. M is S's brother, i.e. M is P's grandfather. \[\Rightarrow \] N is P's sister arid M is N's father, i.e. M is father of P. \[\Rightarrow \] T is P's sister and K is T's father, i.e. K is P's father. And also K is P's brother, i.e. M is P's uncle.
