(i) ${}^{\prime }P\times Q^{\prime }$ means 'P is the brother of Q'.
(ii) ${}^{\prime }P-Q^{\prime }$ means 'P is the sister of Q'.
(iii) ${}^{\prime }P+Q^{\prime }$ means 'P is the father of Q'.
(iv) ${}^{\prime }P÷Q^{\prime }$ means 'P is the mother of Q'.
Which of the following represents 'F is the daughter of W'?

• A. $W÷R+F$
• B. $W\times R\times F$
• C. $W+R\times F-T$
• D. $W+R-F+T$
• E. None of these

Answer 1

The correct option is C $W+R\times F-T$

From option (3),

$W+R\times F-T$
W + R $\to$ W is the father of R.
R $\times$ F $\to$ R is the brother of F.
F - T $\to$ F is the sister of T.
So, F is the daughter of W.
