If $A+B$ means A is the sister of B;

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

$A$ % $B$ means A is the father of B and

$A-B$ means A is the brother of B.

Which of the following means T is the daughter of P ?

• A. $P\times Q$ % $R+S-T$
• B. $P\times Q$ % $R-T+S$
• C. $P\times Q$ % $R+T-S$
• D. $P\times Q$ % $R+S+T$

Answer 1

Answer: (B)

$P\times Q$ % $R-T+S$

$P\times Q\to P$ is the wife of Q

$Q$ % $R\to Q$ is the father of R

$R-T\to R$ is the brother of T

$T+S\to T$ is the sister of S.

Therefore, $T$ is the daughter of $P$.

option B
