Q's mother is P's sister and M's daughter. S is the daughter of P and sister of T. How is M related to T?
A. Mother
B. Father
C. maternal grandmother/paternal grandmother
D. maternal grandfather/paternal grandfather
Answer: Option D
Solution (By JKSSB Mock Tests)
Q's mother is P's sister and M's daughter, so M is parent of P's sister and P. Thus M is grandparent of T (child of P). 'M's daughter' does not specify M's gender, but in such conventional puzzles M is taken as male. Therefore M is either maternal or paternal grandfather of T.
Explanation:
The boy's grandmother's only daughter is the same person as Naveen's grandmother's daughter, meaning both share the same mother. Hence, the boy is Naveen's brother.
A + B means 'A is the mother of B';
A - B means 'A is the husband of B';
A x B means 'A is the son of B';
A + B means 'A is the daughter of B';
If W Ă— Z + Y Ă· X, then how is X related to Z
Explanation:
Z is the mother of Y, and Y is the daughter of X. Thus, X and Z are parents of Y. Based on the relation symbols, X is derived as the corresponding female/daughter relative in the alternate chain.
A * B means 'A is the father of B'. A + B means 'A is the son of B'. A - B means 'A is the brother of B'. A & B means 'A is the sister of B'. If 'W * Q & R - S + T', then what is the relation of W to T?
Explanation:
W is father of Q. Q is sister of R. R is brother of S. S is son of T. Therefore, W is T's father, making W the grandfather of S and ancestor of T's child.
