Question

 If Xis the brother of Y and P, Z is the mother of Y and Q is the father of X, which one of the following statement is not defi nitely true ?

• A. Y is the brother of P
• B. Xis the son of Z
• C. Z is the wife of Q
• D. X is the father of P

Answer 1

The Correct Option is D

To solve the problem, let's analyze the relationships provided in the question:

1. X is the brother of Y and P. This means X, Y, and P are siblings.
2. Z is the mother of Y. Since Y is a sibling of X and P, Z is also the mother of X and P.
3. Q is the father of X. Given X is the brother of Y and P, Q is also the father of Y and P.

Now, let's evaluate each of the options:

1. Y is the brother of P: Since X, Y, and P are siblings and X is the brother, Y could also be a brother. This statement can be true but is not definitely confirmed as their gender is not specified.
2. X is the son of Z: Since Z is the mother of X, X is indeed the son of Z. This statement is definitely true.
3. Z is the wife of Q: Z is the mother and Q is the father of the same children (X, Y, P), so it is highly likely that Z and Q are husband and wife, making this statement definitely true.
4. X is the father of P: This statement is not supported by the information given in the question. X is a sibling of P, not their father. Hence, this statement is not definitely true.

Based on the analysis, the option that is not definitely true is: X is the father of P.
