In a code, 'A @ B' means A is greater than B, 'A # B' means A is less than B, and 'A = B' means A equals B. Given that P @ Q, Q = R and R @ S are all true, which of the following is definitely true?

Competition practiceInequalities
  • A
  • BP @ S
  • CS @ P
  • DQ # S

Step-by-Step Solution

P > Q, Q = R and R > S give P > Q = R > S, so P > S, i.e. P @ S is definitely true.
Answer: B) P @ S
