In the bac of an old cupboard you discover a note signed by a pirate famous for his bizarre sense of humor and love of logical puzzles. In the note he wrote that he had hidden treasure somewhere on the property. He listed five true statements and challenged the reader to use them to figure out the location of the tresure. Where is the treasure hidden?

1. if this house is next to the lake, than the treasure is not in the kitchen
2. if the tree in the front yard is an elm, then the treasure is in the kitchen
3. This house is next to the lake
4. the tree in the front yard is an elm of the treasure is buried under the flagpole
5. if the tree in the backyard is an oak, then the treasure is in the garage.

3. Therefore, using 1, treasure not in kitchen.

2. tree is not elm, since treasure not in kitchen.

not 4, so 5. treasure is in garage.

Actually, all we know is that the tree is not an elm. We have no indication it is an oak. What if it's a maple or a pine?

So, really, we don't know where the treasure is. We just know it's not in the kitchen or under the flagpole.

To determine the location of the treasure, let's break down the statements and analyze the implications:

1. If this house is next to the lake, then the treasure is not in the kitchen.
From this statement, we can conclude that if the house is next to the lake, then the treasure cannot be in the kitchen.

2. If the tree in the front yard is an elm, then the treasure is in the kitchen.
This statement implies that if the tree in the front yard is an elm, then the treasure must be in the kitchen.

3. This house is next to the lake.
This statement confirms that the house is indeed next to the lake.

4. The tree in the front yard is an elm, or the treasure is buried under the flagpole.
This statement implies that if the tree in the front yard is not an elm, the treasure must be buried under the flagpole.

5. If the tree in the backyard is an oak, then the treasure is in the garage.
This statement suggests that if the tree in the backyard is an oak, then the treasure must be in the garage.

Based on these statements, we can make the following inferences:

- The house is next to the lake (Statement 3)
- If the house is next to the lake, the treasure cannot be in the kitchen (Statement 1)
- If the tree in the front yard is an elm, then the treasure is in the kitchen (Statement 2)
- From Statements 1 and 2, we can conclude that the tree in the front yard cannot be an elm because it conflicts with Statement 1

Therefore, the tree in the front yard cannot be an elm. Now let's consider Statement 4:

- If the tree in the front yard is not an elm, then the treasure must be buried under the flagpole.

Since we established that the tree in the front yard is not an elm, the treasure must be buried under the flagpole.

So, in conclusion, the treasure is hidden under the flagpole.

To solve this puzzle and determine the location of the treasure, we need to analyze the given statements.

Let's break them down one by one:

1. "If this house is next to the lake, then the treasure is not in the kitchen."
This means that if the house is next to the lake, the treasure cannot be in the kitchen. So, we can eliminate the kitchen as a potential location if the house is indeed next to the lake.

2. "If the tree in the front yard is an elm, then the treasure is in the kitchen."
This statement implies that if the tree in the front yard is an elm, then the treasure is located in the kitchen. So, if we find out that the tree in the front yard is an elm, the treasure must be in the kitchen.

3. "This house is next to the lake."
According to this statement, the house is indeed next to the lake.

4. "The tree in the front yard is an elm or the treasure is buried under the flagpole."
This statement provides two possibilities:
a) The tree in the front yard is an elm, in which case the treasure is in the kitchen.
b) The tree in the front yard is not an elm, which means the treasure is buried under the flagpole.

5. "If the tree in the backyard is an oak, then the treasure is in the garage."
This statement suggests that if the tree in the backyard is an oak, the treasure is in the garage. However, it doesn't provide any information if the tree is not an oak.

Now, let's put all this information together and analyze the possibilities:

- If the house is not next to the lake, the statements don't give us any indication of the treasure's location.
- If the tree in the front yard is an elm and the house is next to the lake, the treasure is in the kitchen.
- If the tree in the front yard is not an elm, then the treasure is buried under the flagpole.

Given these possibilities, we can conclude that the treasure is either in the kitchen or under the flagpole. We cannot determine its exact location based on the given statements.

So, in order to find the exact location of the treasure, we may need to consider additional clues or solve further puzzles provided by the pirate in the note or explore the property for more information.
