Banking Exams Reasoning — Question 1826

Question

If 'P + Q' means 'P is the father of Q', 'P - Q' means 'P is the mother of Q', and 'P x Q' means 'P is the brother of Q', which expression means 'M is the son of N'?

  1. N + M - T
  2. M x T - N
  3. N - M x T
  4. N x M + T

Correct answer

C — N - M x T

Explanation (English)

'N - M' means N is the mother of M (so M is N's child). 'M x T' means M is the brother of T, confirming M is male. A male child of N is N's son. Thus 'N - M x T' means M is the son of N.
