In a code: 'P % Q' means P ≥ Q; 'P & Q' means P > Q; 'P # Q' means P = Q; 'P @ Q' means P < Q; 'P $ Q' means P ≤ Q. Statement: P # Q, Q $ R. Conclusions: I. R & P.
II. R # P.

  • AOnly conclusion II follows
  • BOnly conclusion I follows
  • CEither conclusion I or II follows
  • DNeither conclusion I nor II follows

Step-by-Step Solution

P # Q is P = Q and Q $ R is Q ≤ R, so R ≥ Q = P means R ≥ P. Thus R > P and R = P each may hold, and together they cover R ≥ P completely, so either I or II follows.
Answer: C) Either conclusion I or II follows
