In a code, 'A @ B' means A is greater than B; 'A # B' means A is less than B; 'A % B' means A is equal to B; 'A & B' means A is greater than or equal to B; 'A * B' means A is less than or equal to B. Given P @ Q, Q & R, R % S, which conclusion is definitely true?

  • AQ < R
  • BP < S
  • CP > S
  • DR > P

Step-by-Step Solution

Decoding gives P > Q ≥ R = S, so P > S. The chain also makes Q ≥ R (not Q < R) and P > R (not R > P), so the other options fail.
Answer: C) P > S
