Persistent Blood Relation Quiz 1

From the question, he mentions, mother’s brother which is his maternal uncle. The mother of the maternal uncle is also his mother’s mother, i.e., his grandmother.
The only daughter of his grandmother is his mother and the only child of hers is him

In the question:- Q * P means that Q is the father of P. Thus, the gender of Q is male so options mother and sister are out.
P - B means that P is the sister of B and B + S means B is the brother of S. Therefore, Q is the father of S.

From the relation
K - M, K is the sister of M
M + O, M is the mother of O
O * L, O is the brother of L
Thus, M is also the mother of L
Then, K is the sister is of M so the aunt of L.

From the equation
P # Q means P is the father of Q, hence P is a male, so option c is out.
Q * R means Q is the brother of R, R - S means R is the sister of S and S * T means S is the brother of T. Hence Q,R,S and T all are siblings with P as their father. Now T + U means T is the mother of U.
Therefore the relation between P and U will be grandfather.

A + B means A is the husband of B, making A male. Hence options b and d are canceled.
Now, B * C means B is the mother of C, and C-D makes C and D siblings with A and B as parents. D * E means D is the mother of E and E # F means E is the daughter of F. Therefore, we can say D and F are married making A the father in law of F.

Solving option M-N+O*P, M-N, M is the sister of N, N + O means N is the brother of O and O* P means P is the son of O. Hence it is wrong option.

From M+N-O*P, M + N makes M brother of N, N-O makes N sister of O. Hence N is a female and cannot be the father.

From M-N*O+P, M - N, means M is the sister of N, N*O means N is the father of O and O + P means O is the brother of P. Therefore, N is also the father of P.

If we check M*N-O+P, M*N means M is the father of N and from further relations, O and P are siblings of N.

From the question, U is V’s parent who is siblings with Q. We know Q and P are sisters, therefore U is also their parent. Now S is P’s mother making U their father. And the relation of S to U is wife.

From the question, we know that A and B are siblings, we do not know the gender of either A or B. Option C is the son of A and B, is wrong as (i) we do not know C’s gender and (ii) A and B are siblings. Option B is the father of D and B is the grandfather of E cannot be determined since we do not know B’s gender.
Option C and D are cousins is definitely true, C and D are cousins, their parents are siblings.

From the given equation, P is the mother of both Q and R who are sisters (female) and S is the child of R. Therefore, R cannot be the father of S as R is a female.
The other options are all true.

U and V are P’s son and M is P’s grandson. And we know U has two children C and D. Therefore M’s father is V.
