Read the following information carefully and answer the questions, which follow:
${}^{\prime }A-B^{\prime }$ means A is the father of B.
$A÷B$ means A is the son of B.
$A\times B$ means A is the wife of B.
Which of the following means T is the wife of P?

• A. $P\times S÷T$
• B. $P÷S\times T$
• C. $P-S÷T$
• D. $P÷T÷S$
• E. None of these

Answer 1

The correct option is E None of these

$P\times S\Rightarrow$ P is wife of S.
$S÷T\Rightarrow S$ is the son of T.
T is either the father-in-law or the mother-in-law of P.
$P÷S\Rightarrow$ P is the son of S.
$S\times T\Rightarrow$ S is the wife of T.
Therefore, T is the father of P.
$P-S\Rightarrow P$ is the father of T.
$P+T\Rightarrow$ P is the daughter of T.
$T÷S\Rightarrow$ T is the son of S.
Therefore, T is the father of P.
