Analyze the inequalities: P ≥ Q, Q > R, S < R, T ≤ Q. Which statement is definitely true?

The correct answer is A: P > S. From the chain: P ≥ Q > R > S and T ≤ Q. Since Q > R > S and P ≥ Q, we get P ≥ Q > R > S, so P > S is definitely true.

Seven friends are seated in a circle. P sits 2 positions to the left of Q. R sits immediately to the right of P. If Q is at position 1, where is R seated?

The correct answer is B: Position 6. Q is at position 1. P sits 2 positions to the left of Q in a circle of 7, so P is at position 7-2=5 (or position 6 counting left). R sits immediately to the right of P, so if P is at 5, R is at 6. Testing: 2 left of 1 in circular = position 7, but recount: P is 2 left means positions go 1→7→6, so P

Four people P, Q, R, S are sitting around a circular table. P is to the left of Q. R is opposite to P. Where is S sitting?
