A is father of O; B is mother of N. The sister of M and O is N. Which ...
“The sister of M and O is N” ⇒ N is female. So calling N “the son of A” is definitely false. The other statements could be true or false depending on whether B is also O’s mother and on M’s gender.
A is father of O; B is mother of N. The sister of M and O is N. Which ...
Understanding the Relationships
To determine which statement is definitely not true, let's analyze the relationships given in the problem:
- A is the father of O.
- B is the mother of N.
- The sister of M and O is N.
Breaking Down the Family Tree
1. A and O: A is the father of O, meaning O is A's child.
2. B and N: B is the mother of N, implying that N is B's child.
3. Siblings: N is the sister of M and O. This means:
- N has a brother, M.
- O is also a sibling of N.
Identifying Relationships
From the statements provided, we can deduce that:
- Since O and N are siblings, and A is the father of O, A is also the father of N.
- Therefore, B (mother of N) must also be the mother of O.
- M, being a sibling of both N and O, suggests that M is also a child of A and B.
Analyzing the Statements
Now let's evaluate the options:
a) B is the mother of O: This is true because O and N are siblings, and B is the mother of N.
b) M is the sister of O: This is false because M is the brother (not sister) of O.
c) N is the son of A: This is definitely not true since N is identified as a sister, hence a daughter of A.
d) B has one daughter: This statement is true because B has at least N as a daughter.
Conclusion
The correct answer is option 'C', as it incorrectly identifies N as a son when N is a daughter. Therefore, this statement is definitely not true.
