\$$ W mean?

X is son's son of Z
Z is father's father of Z
X is son of Z
X is father of Z

Solution:

Condition (1) ⇒ A * B = A is the father of B. So X * Y = X is the father of Y. X is the father.

Condition (2) ⇒ A # B = A is brother of B. So Y #Z = Y is Z’s brother. So X is also the father of Z.

Condition (3) ⇒ A
