If A + B means that A is the father of B, A − B means that A is the brother of B, and A × B means that A is the mother of B, then which of the following expressions shows that P is the maternal uncle of Q ?
P − R × Q
A maternal uncle is the brother of one's mother. So the required expression must say that P is the brother of some person, and that person is the mother of Q.
Step 1 — P − R × Q: P is the brother of R, and R is the mother of Q. P is therefore the brother of Q's mother, i.e. the maternal uncle of Q.
Step 2 — P + R × Q: P is the father of R and R is the mother of Q, so P is Q's maternal grandfather. P − Q + R: P is the brother of Q and Q is the father of R, so P is Q's brother. P × R − Q: P is the mother of R and R is the brother of Q, so P is Q's mother.
Only one expression gives the maternal-uncle relation, so the remaining choice does not apply.
P − R × Q option is correct.
