Therefore, the statement "B and G have only two persons between them" must be false.

In the Mini – World Cup, played at Bulawayo, five cricket teams viz. Australia, South Africa, India, New Zealand and Pakistan participated in the tournament. Each team has to play exactly one match with each of the other teams. If a team wins a match, it is awarded 2 points and gets no points for losing a match. In case a match is a tie, then each of the two teams playing the match would be awarded 1 point. None of the matches scheduled were abandoned.
After the tournament was over, it was known that the total sum of the points scored by some pairs of two teams is as follows:
(i) Australia + India = 12 ; (ii) India + South Africa = 11 ; (iii) New Zealand + India = 10 ; (iv) India + Pakistan = 8.
Also, it is known that there were two ties in the tournament.
Which of the following statements must be true?
Correct Answer
C. South Africa won against Pakistan
Explanation
Based on the given information, we know that India + Pakistan = 8. Since India won against Pakistan, India would have been awarded 2 points, leaving Pakistan with 6 points. Since there were only two ties in the tournament, the remaining points for Pakistan would have come from losing matches. Therefore, Pakistan must have lost all of their matches. Since South Africa won against Pakistan, it is true to say that South Africa won against Pakistan.

Directions : These questions are based on the following data.
Between two persons, A and B, there is one apple and one banana. When I asked them as to who among them had the apple, they gave two statements each in reply.
A: B has the apple. B has the banana.
B: A doesn’t have the banana. A has the apple.
It is known that at least one of A and B tells at least one fale statement.
If it is known that each of A and B tells at least one true statement, then which of the following statements must be true?
Correct Answer
B. Both the statements given by exactly one person out of A and B must be true
Explanation
If both A and B tell the truth, then A's statement that B has the apple and B's statement that A has the apple would both be true, which contradicts the fact that at least one of them tells a false statement. Therefore, both A and B cannot be telling the truth. Since it is known that each of them tells at least one true statement, it means that one of them is telling the truth and the other is lying. Therefore, the statement "Both the statements given by exactly one person out of A and B must be true" must be true.
