Let p: Maths is interesting and q: Maths is easy, then p ⇒ ( p ∨ q)...

Let p:p: Maths is interesting and q:q: Maths is easy, then p⇒(p∨q)isequivalenttop ⇒ \left( p ∨ q\right) is equivalent to

Options

  1. AIf Maths is easy then it is interesting
  2. BEither Maths is interesting or it easy
  3. CIf Maths is interseting then it is easy
  4. DMaths is neither interesting nor easy

Correct answer

C. If Maths is interseting then it is easy

Step-by-step solution

p⇒(p∨q)p ⇒ \left( p ∨ q\right)
≡p∨(p∨q)≡ p ∨ \left( p ∨ q\right)
≡(p∨p)∨q≡ \left( p ∨ p\right) ∨ q
≡p∨q≡ p ∨ q
≡p⇒q≡ p ⇒ q
