Let
$A(x)=x$ is a two wheeler
$B(x)=x$ is a bike
$C(x)=x$ is manufactured by hero.
Which of the following is first order predicate logic for statement
Every bike is a two wheeler manufactured by Hero.
- $∀x(A(x)\land B(x))→C(x)$
- $∀x(A(x)→ B(x))→C(x)$
- $∃ x(A(x)\land B(x))→C(x)$
- $∃ x(A(x)→ B(x))→C(x)$
My attempt:
Given statement can be written as following:
If $x$ is a two wheeler then it is a bike then $x$ is manufactured by Hero
Therefore,
$$∀x(A(x)→ B(x))→C(x)$$
Can you explain in formal way, please?
None of the options is correct. Your reformulation "If $x$ is a two wheeler then it is a bike then $x$ is manufactured by Hero" is also not correct.
The statement can be reformulated as "If $x$ is a bike, then $x$ is a two-wheeler and $x$ is manufactured by Hero", which in formal terms is $\forall x (B(x)\to(A(x)\land C(x))$. None of the options given is equivalent to this statement.
