1.  If P + Q means P is the brother of Q; P x Q means P is the wife of Q and P % Q means P is the daughter of Q then which of the following means D is the uncle of A?
A. A % B x C + D
B. A x B + C % D
C. A + C % B x D
D. None of these

Answer: Option D

Explanation:

A % B means A is daughter of B.

B x C means B is wife of C.

Hence A is daughter of C.

Now C+ D means C is brother of D.

But that does not means D is a male.

i.e. Option D is correct.
