@Ram Swaroop @!KARAN

Have you proceeded in a similar manner like the one given in the link?

Please if possible can either of you elaborate your approach how you reached to this answer.

@Shaik sir, can you please tell how to proceed with such question? If we compare from previous year even the clock is negative edged here.
0
Sorry i didn't seen that, it is negative edge.

I will be back

In this example, clock is independent, so it doesn't effect the result.

For understanding negative clock type question : https://gateoverflow.in/222154/made-easy-test-series

@Shaik sir, In the previous year question does the clock is not independent? Or is it dependent?
0
Clk doesn't depend upon the variables except clock input, so it's independent.
0
CLK A X Y
1 A4 0 A4.0+1.1=1
2 A3 0 A3.0+0.1=0
3 A2 1 A2.1+1.0=A2
4 A1 1 A1.1+A2’.0=A1
5 A0 0 A0.0+A1’.1=A1’

Initially Q=0 & where Y=AX+Q’X’

@Shaik sir please verify whether we have to proceed this way or is there a mistake?

Sometimes converting into eqn doesn't work. ( don't have any examples right now. )

But similar approach you can follow.
