To find: Which of the following statements is true?

a) P is the maternal grandfather of A
b) P is the maternal uncle of A
c) C and P are sisters
d) P and A are cousins

Solution:

From the given information, we can draw the following family tree:

Z
|
Q (sister of C)
|
P (son of Z)
|
A (son of C)
|
C (sister of Q)

So, the correct statement is option (b) - P is the maternal uncle of A.

Explanation:

Maternal uncle is the brother of one's mother. Here, C is the mother of A, so C's brother would be A's maternal uncle.

From the family tree, we can see that P is the son of Z, who is the mother of Q. C and Q are sisters, so P is the brother of A's mother C. Hence, P is the maternal uncle of A.

Therefore, option (b) is the correct statement.

2-Now A is K's son and A's maternal uncle has a child F,
also A has another cousin G which is possibly the child of M&Q.
3-N is father of I who has a sister P(possibly married to K) and P has 2 children one being A and the other is H(since I the maternal uncle of A has one child F).
Therfore, H and G are cousin.

Solution:

Given, T is the mother of I, and I is the mother of H. Therefore, T is the grandmother of H.

Also, H is the daughter of G. Therefore, G is the mother of I's husband or the father of I's child.

Further, G is the brother of Q, and Q is the mother of O. Therefore, G is the maternal uncle of O.

Finally, O is the daughter of J, who is the son of W. Therefore, O is the granddaughter of W.

Therefore, we can conclude that G is the maternal uncle of O and the son-in-law of T.

Hence, the correct answer is option C, i.e., son-in-law.

    Namrata nayar answered
    Let's check all options
    option A:
    P ∗ Q # M $ N
    means P is the sister of Q, who is the mother of M, who is the father of N
    i.e. Q is the mother of M and grandmother of N. P is the sister of grandmother of N.
     
    option B
    P @ Q $ M # N
    means Q is the husband of P, who is the father of M, who is the mother of N.
    P is the father of M and grandfather of N. But Q cannot be P's husband. So, wrong conclusion.
     
    option C:
    P # Q $ N ∗ M  
    means P is the mother of Q, who is the father of N, who is the sister of M.
    Q has 2 kids: N and M.
    P is Q's mother and hence, N's grandmother.
     
    So, none of the option Give the relation that N is the grandmother of P.

    Ameya Joshi answered

    Dev is the only brother of Kitty, and Dolly is the daughter of Kitty. This means:
    - Kitty is the wife of Raman
    - Dev is the brother of Kitty
    - Dolly is the daughter of Kitty

    Maternal Uncle:
    In this scenario, Dev would be considered Dolly's maternal uncle. A maternal uncle is the brother of one's mother. Since Kitty is Dolly's mother, her brother Dev would be Dolly's maternal uncle.
    Therefore, the correct answer is option B) Maternal Uncle.
