QJEEM22Maeb3f: JEE Main 2022 Mathematics - Class 11 JEEM22Maeb3f Solution: The negation of the Boolean expression (( q) p) (( p) q) is…

The negation of the Boolean expression (( ∼\sim q) ∧\wedge p) ⇒\Rightarrow (( ∼\sim p) ∨\vee q) is logically equivalent to :

Multiple Choice Options

  • A p⇒qp \Rightarrow q
  • B q⇒pq \Rightarrow p
  • C ∼(p⇒q)\sim (p \Rightarrow q)
  • D ∼(q⇒p)\sim (q \Rightarrow p)

Step-by-Step Verified Solution

Let S:((∼q)∧p)⇒((∼p)∨q)S:(( \sim q) \wedge p) \Rightarrow (( \sim p) \vee q)

⇒S: ∼((∼q)∧p)∨((∼p)∨q)\Rightarrow S:\, \sim (( \sim q) \wedge p) \vee (( \sim p) \vee q)

⇒S:(q∨(∼p))∨((∼p)∨q)\Rightarrow S:(q \vee ( \sim p)) \vee (( \sim p) \vee q)

⇒S:(∼p)∨q\Rightarrow S:( \sim p) \vee q

⇒S:p⇒q\Rightarrow S:p \Rightarrow q

So, negation of S will be ∼(p⇒q)\sim (p \Rightarrow q)
