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, wich 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 ‘$’.

6) Answer (C)

In, order to tackle this question, we intrepret the equation in reverse manner.
Now, $R\ge$ 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.
7) Answer (C)

A-B means B is brother of A.

Q $\ge$ 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.
8) Answer (A)

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

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

Y $★$ 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.

9) Answer (A)

p$\times$ Q $\le$ R $★$ S

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

Q $\le$ 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.

10) Answer (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.

11) Answer (D)

the expression ${}^{\prime }A\le P\times T+F\ge L\times M^{\prime }$ 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.

12) Answer (A)

$M+N★P\ge A$, 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.

13) Answer (B)

$Q\times P\le B+F$ 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.

14) Answer (C)

$R\ge S★P$ ¬ $J$ 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.

15) Answer (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.

16) Answer (A)

In the expression, J ÷

÷

P % H ? T % L

J is son of P and P is mother of H, => J is brother of H

Now, for J to be brother of T, T must be a sibling of H.

The only option available is ‘x’

After that , H is sister of T, and hence J is brother of T

Ans – (A)

17) Answer (B)

(A) : L % R $ D + T x M = L is the mother of R, who is wife of D. D is father of T, who is sister of M.

=> Gender of M is not known. M can be son/daughter of D.

(B) : L + R $ D + M x T = L is father of R, who is wife of D. D is father of M, who is sister of T.

=> M is female and hence daughter of D.

(C) L % R % D + T $÷$ M = L is mother of R, who is mother of D. D is father of T and T is son of M

=> M is wife of D

(D) D + L $ R + M x T = D is father of L, who is wife of R. R is father of M, who is sister of T.

=> M is granddaughter of D

(E) L $D$\div$R$\div$ T = L is wife of D, who is son of R. R is mother of M, who is son of T.

=> M is brother of D

Thus, Ans – (B)

18) Answer (B)

I + T % J x L $÷$ K implies I is the father of T and T is the mother of J and J is the sister of L and L is the son of K.

1) L is the son of K. So, L is male. So, (a) is incorrect

3) I is the father of T. So, I is male. So, (c) is incorrect.

4) T is the mother of J. So, T is female. So, (d) is incorrect

5) J is the sister of L. So, J is female. So, (e) is incorrect.

 

The correct answr is (b)

 

19) Answer (D)

(A) : W % L x T x Y $÷$ X = From the last part of the expression, it is clearly known that Y is son of X [ Y $÷$ X]

(B) : W + L x T x Y $÷$ X = From the last part of the expression, it is clearly known that Y is son of X [ Y $÷$ X]

(C) : X + L x T x Y $÷$ W = X is father of L, who is sister of T, who is sister of Y, and Y is son of W

=> W is the wife of X and hence Y is the son of X

(D) W $ X + L + Y + T = W is the wife of X, who is father of L, who is father of Y, who is father of T.

=> Y is the grandson of X

(E) W % X + T x Y $÷$ L = W is mother of X, who is father of T and T is sister of Y, who is son of L

=> L is the wife of X and hence Y is the son of X.

Only, in (D) the expression is false.

20) Answer (D)

In the expression, R % T x P ? Q + V

R is the mother of T and T is the sister of P.

Now, for T to be the sister in law of Q, => Q must be married to P.

The only option available for that is ‘$’

=> Now, P is wife of Q and hence T is sister-in-law of Q

Ans – (D)
