If ‘S – T’ means ‘S is the wife of T’; ‘S + T’ means ‘S is the daughter of T’ and ‘S ÷ T’ means ‘S is the son of T’. What will ‘M + J ÷ K’ means?

If ‘A + B’ means ‘A is the mother of B’; ‘A – B’ means ‘A is the brother of B’; ‘A % B’ means ‘A is the father of B’ and ‘A × B’ means ‘A is the sister of B’. Which of the following shows that ‘P is the maternal uncle of Q’?

In answer choice ‘P – M + N × Q’:
P – M → P is the brother of M
M + N → M is the mother of N
N × Q → N is the sister of Q.
Therefore, P is the maternal uncle of Q.

If ‘A + B’ means ‘A is the brother of B’; ‘A ÷ B’ means ‘A is the father of B’ and ‘A × B’ means ‘A is the sister of B’. Which of the following means ‘M is the uncle of P’?

‘M is the uncle of P’ means M is the brother of the father (say K) of the sister (say T) of P, i.e., M + K ÷ T × P.

If ‘P + Q’ means ‘P is the brother of Q’; ‘P × Q’ means ‘P is the father of Q’; ‘P – Q’ means ‘P is the sister of Q’. Which of the following represents ‘S is the niece of T’?

‘S is the niece of T’ means ‘T is the brother of the father (say M) of S’.
i.e., T + M × S.

‘P × Q’ means ‘P is the sister of Q’; ‘P + Q’ means ‘P is the father of Q’; ‘P – Q’ means ‘P is the mother of Q’. Which of the following means ‘S is the aunt of T’?

S is the aunt of T means S is the sister of the father (say M) of T.
i.e., S × M + T.

If ‘A + B’ means ‘A is the brother of B’; ‘A – B’ means ‘A is the sister of B’; ‘A × B’ means ‘A is the wife of B’ and ‘A ÷ B’ means ‘A is the father of B’ then which of the following indicates ‘S is the son of P’?

As ‘S’ is female in the first two answer choices, they can be rejected directly. The gender of ‘S’ in the third answer choice is not known, hence it can also be eliminated. Now, in the last answer choice ‘P × Q ÷ R – S + T’ means P is the wife of Q, Q is the father of R, R is the sister of S and S is the brother of T. i.e., S is the son of P.

‘A $ B’ means ‘B is father of A’; ‘A # B’ means ‘B is mother of A’; ‘A* B’ means ‘B is sister of A’ and ‘A @ B’ means ‘B is husband of A’; then which of the following indicates the relationship ‘N is grandmother of P’?

N is the mother of M, M is the husband of Q, Q is the mother of P ⇒ N is the grandmother of P. i.e., P # Q @ M # N.

If ‘M × N’ means ‘M is the daughter of N’; ‘M + N’ means ‘M is the father of N’; ‘M ÷ N’ means ‘M is the mother of N’ and ‘M – N’ means ‘M is the brother of N’ then in the expression ‘P÷ Q + R – T × K’, how ‘P is related to K’?

P ÷ Q + R – T × K means P is the mother of Q, Q is the father of R, R is the brother of T and T is the daughter of K.
⇒ Q is the husband of K and therefore P is the mother-in-law of K.

‘P – Q’ means ‘Q is the son of P’; ‘P × Q’ means ‘P is the brother of Q’; ‘P ÷ Q’ means ‘Q is the sister of P’ and ‘P + Q’ means ‘P is the mother of Q. Which of the following is definitely TRUE about ‘N × K – M ÷ L’?

N × K – M ÷ L ⇒ N is the brother of K, M is the son of K, L is the sister of M.
Since we don't know the gender of K, therefore, first and third answer choices are not definitely true. Since M is the son of K, therefore, the fourth answer choice is not true. Now, since L is the sister of M, therefore, L is the daughter of K. Also, N is the brother of K, therefore L is the niece of N.

If ‘P × Q’ means ‘Q is the mother of P’; ‘P + Q’ means ‘P is the brother of Q’; ‘P – Q’ means ‘P is the sister of Q’ and ‘P ÷ Q’ means ‘Q is the father of P’. Then, which of the following definitely means ‘R is the grandson of K’?

Reject 1st, 2nd and 3rd answer choices because the equation does not tell about the gender of R.

If ‘P = Q’ means ‘Q is the father of P’; ‘P * Q’ means ‘P is the sister of Q’; ‘P ? Q’ means ‘Q is the mother of P’; ‘P $ Q’ means ‘P is the brother of Q’; ‘P @ Q’ means ‘Q is the son of P’; and ‘P × Q’ means ‘P is the daughter of Q’. Then which of the following is not correct?

‘R × S ? T’ means R is the daughter of S whose mother is T i.e., R is the granddaughter of T.
‘P = Q ? R’ means R is the mother of Q who is the father of P i.e., R is the grandmother of P.
‘L $ M * O’ means L is the brother of M who is the sister of O i.e., L is the brother of O i.e., O is the brother or sister of L.
‘M * O @ P = Q’ means Q is the father of the son (P) of O. i.e., Q is the father and O is the mother of P. i.e., Q and O are husband and wife.

If ‘P $ Q’ means ‘P is the father of Q’; ‘P # Q’ means ‘P is the mother of Q’ and ‘P * Q’ means ‘P is the sister of Q’. Then how is ‘Q related to N’ if ‘N # L $ P * Q’?

The gender of Q is not given hence the exact relationship between N and Q cannot be established.

Directions (Q.1/5): ‘A × B’ means ‘A is the mother of B’. ‘A – B’ means ‘A is the brother of B’. ‘A + B’ means ‘A is the sister of B’. ‘A ÷ B’ means ‘A is the father of B’.
