If

$A+B$ means $A$ is the brother of $B$,

$A-B$ means $A$ is the father of $B$,

$A\times B$ means $A$ is the wife of $B$,

then $P\times R-S+T$ means

• A. $P$ is the mother of $T$
• B. $T$ is the sister of $P$
• C. $R$ is the grand father of $T$
• D. $T$ and $R$ are sisters

Answer 1

The correct option is A $P$ is the mother of $T$

$P\times R-S+T$ means
$P\times R$ means $P$ is the wife of $R$
$R-S$ means $R$ is father of $S$.
$S+T$ means $S$ is brother of $T$
Then,

$R$ and $P$ are the father and mother of $S$ and $T$.

So, $P$ is the mother of $T$.

option A.
