machn can you help me to find the answer?

Question:
“Anyone who own lands or vehicles will pay tax. Some people do not own vehicles but pay tax. It is not the case that some peoples pay taxes.”

1.) Write the above paragraph in first order logic and convert them into the conjunctive normal form.

2.) By considering the paragraph in Part (1) Sarath argues that Kamal does not own a vehicle. Do you agree with Sarath? Using the method of contradiction justify your answer.

1.) First-order logic representation:

L(x) - "x owns lands" V(x) - "x owns vehicles" T(x) - "x pays tax"

∀x (L(x) ∨ V(x) → T(x)) ∃x (¬V(x) ∧ T(x)) ¬∃x T(x)

Conjunctive normal form (CNF):

(¬L(x) ∨ ¬V(x) ∨ T(x)) (¬V(x) ∨ T(x)) ¬T(x)

2.) Sarath argues that Kamal does not own a vehicle. To justify this using the method of contradiction, let's assume that Kamal does own a vehicle (V(Kamal)).

From the given information, we have: ∀x (L(x) ∨ V(x) → T(x)) ∃x (¬V(x) ∧ T(x)) ¬∃x T(x)

By substituting Kamal for x, we can derive the following: (L(Kamal) ∨ V(Kamal) → T(Kamal)) (¬V(Kamal) ∧ T(Kamal)) ¬T(Kamal)

Now, we have the assumption V(Kamal) and the derived statement (¬V(Kamal) ∧ T(Kamal)). This leads to a contradiction since Kamal cannot both own a vehicle and not own a vehicle at the same time.

Therefore, based on the method of contradiction, we can conclude that Sarath's argument is correct, and Kamal does not own a vehicle.

Generated using GPT-4

Let's first rewrite the statements into First-Order Logic.

We need to define a few predicates:

• OwnsLand(x): x owns land
• OwnsVehicle(x): x owns a vehicle
• PaysTax(x): x pays tax

Now, the given sentences can be translated into first-order logic as follows:

1. ∀x [(OwnsLand(x) ∨ OwnsVehicle(x)) → PaysTax(x)]
2. ∃x [¬OwnsVehicle(x) ∧ PaysTax(x)]
3. ¬∃x [PaysTax(x)]

The conjunctive normal form (CNF) of these statements would be:

1. ∀x [¬OwnsLand(x) ∧ ¬OwnsVehicle(x)] ∨ PaysTax(x)
2. ∃x [¬OwnsVehicle(x) ∧ PaysTax(x)]
3. ¬∃x [PaysTax(x)]

This can further be simplified to:

1. ∀x [¬OwnsLand(x) ∨ PaysTax(x)] ∧ [¬OwnsVehicle(x) ∨ PaysTax(x)]
2. ∃x [¬OwnsVehicle(x) ∧ PaysTax(x)]
3. ¬∃x [PaysTax(x)]

So, the conjunctive normal form (CNF) of these statements are:

1. ∀x [(¬OwnsLand(x) ∨ PaysTax(x)) ∧ (¬OwnsVehicle(x) ∨ PaysTax(x))]
2. ∃x [¬OwnsVehicle(x) ∧ PaysTax(x)]
3. ¬∃x [PaysTax(x)]

Note: Here, I have used the property that (P → Q) is equivalent to (¬P ∨ Q) to convert the statements into CNF.

For the second part, if Sarath argues that Kamal does not own a vehicle, let's assume the opposite and see if it leads to a contradiction.

Assumption: Kamal owns a vehicle.

Given the logic rules:

1. If Kamal owns a vehicle or land, he should pay tax (From first rule)
2. There exist some people who don't own a vehicle but pay tax (From second rule)
3. There are no people who pay tax (From third rule)

From assumption and rule 1, Kamal should pay tax. However, rule 3 states that no one pays tax, which contradicts our conclusion that Kamal should pay tax. Hence, the assumption is wrong, and Sarath is correct to argue that Kamal does not own a vehicle.
