Problem Analysis

We are given a scenario where five boys are talking about the ownership of a ball. Each boy makes a statement about who has the ball. We need to determine which boy is lying.

Solution

To solve this problem, let's analyze each boy's statement and check for inconsistencies.

1. Alesha says, "I don't have the ball." 2. Borya says, "I have the ball." 3. Vitya says, "Dani has the ball." 4. Gosha says, "I don't have the ball." 5. Danya says, "Alesha has the ball."

Let's evaluate each statement one by one:

1. Alesha says, "I don't have the ball." - If Alesha is telling the truth, then no one has the ball. - If Alesha is lying, then someone else has the ball. - We cannot determine the truthfulness of this statement based on the given information.

2. Borya says, "I have the ball." - If Borya is telling the truth, then he has the ball. - If Borya is lying, then someone else has the ball. - We cannot determine the truthfulness of this statement based on the given information.

3. Vitya says, "Dani has the ball." - If Vitya is telling the truth, then Dani has the ball. - If Vitya is lying, then someone else has the ball. - We cannot determine the truthfulness of this statement based on the given information.

4. Gosha says, "I don't have the ball." - If Gosha is telling the truth, then no one has the ball. - If Gosha is lying, then someone else has the ball. - We cannot determine the truthfulness of this statement based on the given information.

5. Danya says, "Alesha has the ball." - If Danya is telling the truth, then Alesha has the ball. - If Danya is lying, then someone else has the ball. - We cannot determine the truthfulness of this statement based on the given information.

Based on the given information, we cannot determine which boy is lying. There is not enough information to make a conclusive decision.
