In a certain code, ‘P ★ Q’ means ‘P is greater than Q’; ‘P $ Q’ means ‘P is smaller than Q’; ‘P * Q’ means ‘P is equal to Q’; ‘P @ Q’ means ‘P is greater than or equal to Q’; ‘P © Q’ means ‘P is smaller than or equal to Q’. If A * Q, G @ B, S ★ G, B @ A, which of the following is definitely true?
Correct answer D. Q $ S
Explanation
Decoding the statements gives the chain S > G ≥ B ≥ A = Q. Hence Q < S, which is written as Q $ S. The other relations are possible but not certain.
