Question:

There is a family of five members: K, L, M, N and O. Among them, there is one married couple. O is unmarried and is the brother of K, N is the sister of O, M is the only married female and the mother of N. L and O are the only males in the group. Who is the father of K?

Options:

O

K

M

L

Correct Answer:

L

Explanation:

The correct answer is Option (4) → L

1. Identify the Generations and Genders

  • M is the mother of N: This means M is from the older generation and N is from the younger generation.
  • M is the only married female: Since there is one married couple, M must be the wife.
  • L and O are the only males: This tells us the gender of everyone else.
    • Males: L, O
    • Females: M, N, K (Since M is the only married female, K and N must be unmarried females).

2. Establish the Siblings

  • O is the brother of K.
  • N is the sister of O.
  • Therefore, K, N, and O are all siblings (the children's generation).

3. Identify the Parents

  • We know M is the mother of N, so M is also the mother of K and O.
  • Since M is the "only married female" and the mother, her husband must be the father of the children.
  • From the male list (L and O), we know O is a sibling (the son).
  • This leaves L as the only person who can be the husband of M and the father of the children.

Conclusion

  • Father: L
  • Mother: M
  • Children: K (Female), N (Female), O (Male)

Answer: The father of K is L
