In a code, '+' means ≥, '−' means ≤, '×' means >, '÷' means <, and '=' means =. Statements: P = Q, Q ≥ R (Q + R). Conclusions: I. P × R (P > R).
II. P = R.

  • AOnly I is true
  • BEither I or II is true
  • COnly II is true
  • DNeither is true

Step-by-Step Solution

P = Q ≥ R gives P ≥ R, which means either P > R or P = R. Neither is individually certain, but together they are exhaustive, so either I or II is true.
Answer: B) Either I or II is true
