P, Q, and R talk about S's car collection, P states that S has at least 3 cars. Q believes that S has less than 3 cars, R says that to his knowledge, S has at least one car. Only one of P, Q and R is right. The number of cars owned by S is
 0
 1
 3
 Cannot be determined
Correct Option : A
According to P, S > = 3
According to Q, S < 3
According to R, S > = 1
From this we get that P's and Q's statements contradict each other while R supports the statement of P. However, only one among them is right so it has to be Q when S has zero cars.
