Q41 / 69 · NTA Abhyas (JEE Main) 2020 · Mathematics · Mathematical Reasoning

If $p \Rightarrow (q \lor r)$ is $F a l s e$ , then the truth values of $p, q, r$ are respectively (where $T$ is $T r u e$ and $F$ is $F a l s e$ )

Correct answer
A
$T, F, F$
B
$F, T, T$
C
$F, F, F$
D
$T, T, F$

Solution

p \Rightarrow (q \lor r) : F a l s e

p : T r u e; q \lor r : F a l s e

p : T r u e; q : F a l s e; r : F a l s e

Hence, the correct answer is option: 'A'.
