If A + B means A is the sister of B; A x B means A is the wife of B, A % B means A is the father of B and A - B means A is the brother of B. Which of the following means T is the daughter of P?

  • A.
    P x Q % R + S - T
  • B.P x Q % R - T + S
  • C.P x Q % R + T - S
  • D.P x Q % R + S + T

Answer: B

Correct answer: P x Q % R - T + S

P × Q makes P the wife of Q; Q % R makes Q the father of R; R – T makes R the brother of T, so T is Q’s child; and T + S makes T the sister of S, showing T is female. A daughter of Q is a daughter of his wife P.
