If D is the brother of B, how B is related to C? To answer this question which of the statements is/are necessary?
1.The son of D is the grandson of C.
2.B is the sister of D.
Given: D is the brother of B.
From statement 1, we can detect that D is son of C (son of D is the grandson of C).
From statement 2, we can detect that B is 'Female' (sister of D).
Therefore, B is daughter of C.
Introducing a boy, a girl said, “He is the son of the daughter of the father of my uncle.” How is the boy related to the girl?
The father of the girl's uncle is the grandfather of the girl and daughter of the grandfather is sister of her father.
So, daughter of the grandfather is her aunt.
Aunt's son is brother of the girl.
Hence, option A is correct.
If A is the brother of B; B is the sister of C; and C is the father of D, how D is related to A?
If D is Male, the answer is Nephew.
If D is Female, the answer is Niece.
As the sex of D is not known, hence, the relation between D and A cannot be determined.
If A + B means A is the father of B; A – B means A is the brother B; A % B means A is the wife of B and A x B means A is the mother of B, which of the following shows that M is the maternal grandmother of T?
M x N → M is the mother of N
N % S → N is the wife of S
and S + T → is the father of T.
Hence, M is the maternal grandmother of T.
If A + B means A is the brother of B; A x B means A is the son of B; and A % B means B is the daughter of A then which f the following means M is the maternal uncle of N?
Because the sex of O is not known.
