Question

X is the brother of Y.
Y is the brother of Z.
W is the father of X.
Based on these three statements, which of the following statements is/are true?

• A. Y is the son of W.
• B. Z is the wife of W.
• C. Both (a) and (b)
• D. Y is the brother of X.

Answer 1

The correct option is C Both (a) and (b)

Let's draw a family tree to understand the relationship between W, X, Y, and Z.

X is the brother of Y, and Y is the brother of Z.
It is clear from these statements that X, Y, and Z are siblings.

Now, W is the father of X.
So, W is the father of X, Y, and Z.


The gender of Z is not revealed.
So, Z can either be the brother or sister of X.

Now, let's look at the statements.

The first statement says that Y is the brother of X, which is true.

The second statement says that Y is the son of W, which is also true.

The third statement says that Z is the wife of W, which is not true.

Hence, both options (a) and (b) are true.
