@tskushagra-guptacse , yes all DM questions are uploaded.

commented Jul 1 by tsvikasthamke2095 (320 points)

Click on discreet mathematics

commented Jul 1 by tsnikhilsharmagate2018 (31,600 points)

Now all questions are updated

commented Jul 1 by tsnikhilsharmagate2018 (31,600 points)

$\\ \forall x(P(x)\rightarrow A)=\exists xP(x)\rightarrow A\\ (P1\rightarrow A).(P2\rightarrow A)=(P1+P2)\rightarrow A\\ (P1'+A).(P2'+A)=(P1+P2)'+A\\ P1'P2'+A=P1'P2'+A\\ \\ \exists x(P(x)\rightarrow A )=\forall x P(x)\rightarrow A\\ (P1\rightarrow A)+(P2\rightarrow A)=P1P2\rightarrow A\\ (P1'+A)+(P2'+A)=(P1P2)'+A\\ P1'+P2'+A=P1'+P2'+A\\$

Therefore ans should be C

you are correct bhai ,I have made mistake in this question

commented Jun 30 by tsankitjha910 (3,730 points)

You r correct bro.

commented Jun 30 by tsnikhilsharmagate2018 (31,600 points)

In the first one, shouldn't there be a term (P1' + P2')A? Where did that go?

commented Jun 30 by tsgokulnath136 (5,330 points)

I have given the final result.
Do like this: P1'P2'+P1'A+P2'A+A
                      P1'P2'+P1'A+(P2'+1)A
                      P1'P2'+P1'A+A
                      P1'P2'+(P1'+1)A
                      P1'P2'+A

commented Jun 30 by tskushagra-guptacse (15,960 points)

C is the answer

For problem 11

commented Jul 1 by tsnikhilsharmagate2018 (31,600 points)

@tsnikhilsharmagate2018 none of these both are satisfiable.
