Question 15: What should come in place of the question mark, to establish that J is the brother of T in the expression?
\div P % H ? T % L

a) x

b) $\div$

c) $d) Either$\div$or x e) Either + or$\div$Answers & Solutions: 1) Answer (A) J ÷ P % H ? T % L => T is the mother of L and J is the brother of H Now, for J to be brother of T, H must be either sister or brother of T. => ‘x’ is the correct symbol here. 2) Answer (B) In option B, D + M is given, which implies that D is the father of M. Now, if M is a girl, then it can be established that M is the daughter of M. M x T => M is a sister of T => M is a girl Hence option B is correct. 3) Answer (B) I + T % J × L ÷ K L ÷ K => L is the son of K J × L ÷ K => J is the daughter of K T % J × L ÷ K => T is the wife of K I + T % J × L ÷ K => I is the father-in-law of K Hence B is the correct answer 4) Answer (D) Given that Y is not a son of X. In option A and B, Y ÷ X is given, which is wrong. Hence A and B are eliminated. In option C, X + L x T x Y is given => X is father of Y, which is wrong. Hence C is eliminated. Similarly E can also be eliminated. Hence, D is the answer 5) Answer (D) T × P ? Q Here, T is the sister of P. So for T to be sister-in-law of Q, P must be Q’s wife. Hence the correct symbol is ‘$’.

In, order to tackle this question, we intrepret the equation in reverse manner.
Now, $R \geq$ S means S is father of R.
B+R means R is sister of B which means S is also father of B.
Now, AxB means B is son of A, but then B is also son of A.
Hence, A is wife of S.
Hence, option is C.

W $\geq$ X means W is son of X.

X $\leq$ Y means X is daughter of Y.

Y $\bigstar$ Z means Y is mother of Z which means X and Z are siblings. Also, W is son of X which means Z is uncle/aunt of W and W is nephew of Z.

Hence, correct option is A.

p$\times$ Q $\leq$ R $\bigstar$ S

Now, R $\bigstar$ S means S is son/daughter of R.

Q $\leq$ R means R is father or mother of Q. hence, S and Q are siblings.

p$\times$ Q means Q is son\daughter of P. S is son/daughter of P as S and Q are siblings. Hence S is parent to P.

Hence, the correct option is A.

None of the options establish a relation of C being nephew of D or D being aunt of C.
Hence, none of the option is correct.
The correct option in this case is E.

the expression $’A\leq P \times T + F \geq L \times M’$ is intrepreted as A is daughter of P, P is husband of T, T is sister of F. Hence, T is mother of A and A is niece of T.

Therefore, correct option is D.

$M + N \bigstar P \geq A$, M is sister of N, N is wife of P, P is son of A. Hence, A is mother of P and N is daughter in law of A.

Hence, the correct option is A.

$Q \times P\leq B + F$ can be intrepreted as:
Q is husband of P, P is daughter of B, B is sister of F. Hence, F is uncle/aunt of P or P is niece of F.

B is the correct option.

$R\geq S \bigstar P$ ¬ $J$ can be interpreted as:
R is son of S. S is wife of P, hence, R is son of P i.e P is father of R.
Hence, the correct option is C.

Here, if we try to intrepret the relation: A \$ \bigstar B\geq Z \times S + M
B is son of Z. Z is wife of S. S is sister of M. However, anomaly is that if Z is wife of S then S is husband and male member. However it is also mentioned that
S is sister. Hence, S is assumed to be female member which is in contradiction to previous designation.
Therefore, we cannot determine the relation between B and M.
