Question

Nalini, her brother, her daughter and her son are tennis players and are playing game of doubles. Their positions on the court are as follows: Nalini's brother is directly across the net from her daughter. Her son is diagonally across the net from the worst player's sibling. The best player and the worst players are on the same side of the net. Who is the best players?

• A. Nalini
• B. Nalini's brother
• C. Nalini's daughter
• D. None of these

Answer 1

The Correct Option is B

To solve the problem, we must analyze the given information about the positions and relationships of the players. Let's break it down step by step:

1. There are four players: Nalini, her brother, her daughter, and her son.
2. Nalini's brother is directly across the net from her daughter.
3. Her son is diagonally across the net from the worst player's sibling.
4. The best and worst players are on the same side of the net.

Let's denote the positions on the court as follows for clarity:

• Side 1: A and B
• Side 2: C and D

1. From the first point, if Nalini's brother (say, A) is directly across from Nalini's daughter (say, C), they are on opposite sides: A is on Side 1, and C is on Side 2.

2. Now, Nalini's son is diagonally across from the worst player's sibling. This indicates that the son cannot be on the same pairing with his sibling (Nalini's daughter, C). So, Nalini's son (say, B) is therefore on Side 1, paired with Nalini's brother (A).

• Side 1: Nalini's brother (A), Nalini's son (B)
• Side 2: Nalini's daughter (C), Nalini (D)

3. The best and the worst players are on the same side. Nalini's son, who is not mentioned directly within these constraints implying that he is neither the best nor the worst. Thus, either Nalini's brother (A) or her daughter (C) must be the best and worst players.

Since Nalini's brother and daughter are directly opposite each other, then by deduction, the pairing tells us the best player by default through elimination and reasoning based on typical logic puzzles. Also considering typical family dynamics where siblings can often excel in the same activity, it's logical that the brother is the best player. Therefore, the position of the players hints strongly toward the arrangement where Nalini's brother is the best player, complying with the condition that the best and worst are on the same side.

Thus, the best player is Nalini's brother.
