If truth value of logical statement $(p \leftrightarrow \sim q) \rightarrow(\sim p \wedge q)$ is false, then the truth values of $\mathrm{p}$ and $\mathrm{q}$ are respectively
  1. $\mathrm{F}, \mathrm{T}$
  2. $\mathrm{T}, \mathrm{T}$
  3. $\mathrm{T}, \mathrm{F}$
  4. $\mathrm{F}, \mathrm{F}$

Solution

As $(p \leftrightarrow \sim q) \rightarrow(\sim p \wedge q)$ is false, we get $p \leftrightarrow \sim q \equiv T$ and $\sim p \wedge q \equiv F$ $\sim p \wedge q=F$ $\Rightarrow \sim \mathrm{p} \equiv \mathrm{F}$ and $\mathrm{q} \equiv \mathrm{F}$ $\Rightarrow \mathrm{p} \equiv \mathrm{T}$ and $\mathrm{q} \equiv \mathrm{F}$
