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. 2)Â AnswerÂ (C) A-B means B is brother of A. Q$\geq$A means A is father of Q and Q is niece of B. P+Q means P is sister of Q which also means P is niece of B. Hence, the correct option is option C. 3)Â AnswerÂ (A) 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. 4)Â AnswerÂ (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. 5)Â AnswerÂ (E) 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. 6)Â AnswerÂ (D) 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. 7)Â AnswerÂ (A)$ M + N \bigstar P \geq A$, M is sister of N, N is wife of P, P is son of A. Hence, A is mother of P and N is daughter in law of A. Hence, the correct option is A. 8)Â AnswerÂ (B)$Q \times P\leq B + F $can be intrepreted as: Q is husband of P, P is daughter of B, B is sister of F. Hence, F is uncle/aunt of P or P is niece of F. B is the correct option. 9)Â AnswerÂ (C)$ R\geq S \bigstar P$Â¬$J$can be interpreted as: R is son of S. S is wife of P, hence, R is son of P i.e P is father of R. Hence, the correct option is C. 10)Â AnswerÂ (E) Here, if we try to intrepret the relation: A$ \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.

(A) : H*T%K = H is sister of T and T is father of K, => T is male

=> T is brother of H

(B) : T*H%K = T is sister of H, who is father of K

=> T is sister of H

(C) : H#K%T = H is the son of K and K is also father of T, => gender of T is unknown

=> T can be either brother or sister of H

(D) : H*K%T = H is sister of K, who is father of T

=> T is either nephew or niece of H

Ans – (A)

In H*T#F%L

H is sister of T, who is son of F.

F is father of L, => H(female), T(male) & L are siblings.

=> H is sister of L

(A) : M*J#K$R = M is the sister of J, who is son of K. K is the wife of R => R is father of J (B) : M*R$K%J = M is sister of R, who is wife of K. K is father of J

=> R is mother of J

(C) : J#R#T = J is son of R, who is son of T

=> R is father of J

(D) : R$K%M$J = R is wife of K, who is father of M. M is wife of J.

=> R is mother-in-law of J.

Ans – (B)

Option A: J X T + R means that J is the brother of T who is the mother of R. The gender of R cannot be determined ( R can be nephew/niece).

Option B: K X R – J means that K is the brother of R who is the sister of J. All three of them are siblings.

Option C: J X T + R $\div$ K means that J is the brother of T. T is the mother of R. R is the father of K. Hence, J is the uncle of R. But the question asks whether J is the nephew of R.

Option D: J X T – R means that J is the brother of R. hence, the required relationship is not obtained.

Therefore, the correct answer is option E – none of the above.
