Finding Blood Relations: O and N

This question asks us to determine the relationship between O and N based on the given information about family connections. Let's break down the relationships step by step:

  • L is the mother of K.
  • L is the sister of N.
  • K is the sister of O.
  • P is the husband of O.
  • N is the husband of M.

From the first three statements, we can establish the relationship between L, K, and O:

  • L is the mother of K.
  • K is the sister of O.

This means that K and O are siblings, and L is their mother. So, L is the mother of both K and O.

Now, let's connect this to N:

  • L is the sister of N.
  • L is the mother of O.

Since L is O's mother and L is N's sister, N is the sibling of O's mother. This makes N O's maternal uncle (mama) or maternal aunt (mausi). The statement "N is the husband of M" tells us N is male.

Therefore, N is O's maternal uncle.

We need to find how O is related to N. If N is O's maternal uncle, then O is the child of N's sister. A daughter of a person's sister is called a niece.

Since O is a sibling of K (and K is female), O could be male or female based on the first few statements alone. However, the statement "P is the husband of O" clarifies that O is female.

So, O is the daughter of L, who is N's sister. Thus, O is N's niece.

We can summarize the key relationships relevant to O and N:

  • L: O's mother
  • L: N's sister

This clearly shows O is the daughter of N's sister.

Individual Relation Gender
L Mother of K and O; Sister of N Female
K Sister of O; Daughter of L Female
O Sister of K; Daughter of L; Wife of P Female
N Brother of L; Husband of M Male

Based on the table, O is the daughter of L, and L is the sister of N. Therefore, O is the niece of N.
