Director ME, stop copying answers from GO. Make your own(correct) key (if you can). 
Answers without explanation, people are paying just for this. Really??

Official GATE key : https://drive.google.com/file/d/1whFDTWVWev3NZLRwNVPHTXQG-n_9b3D6/view

NO CHANGE :)

 

Edit: After challenge, range modified for question number 25. Previously it was 34 now 34 to 35.

@Digvijay Pandey  sir

GO is always better than others

100% accuracy is Awesome :) Arjun sir _/\_
Did the official people out there just copy all answer keys from GateOverflow ? @Arjun Sir, @Bikram Sir, @Digvijay Pandey Sir, you are aweeeesomeee!!!
Definitely, GATE officials didn't copy but yes prominent (:-P) coaching centers and some self-proclaimed 'God Father of CSE GATE' copied answers from GO.

according to me @ Digvijay Pandey answer of Q36 can be option A  

https://gateoverflow.in/204110/gate2018-36

can you(any one) please give me concrete explanation even though official key also says option D.

Thanks :)

3rd OptionGiven two grammar G1 and G2, whether L(G1) = L(G2) 

is Undecidable. Because When nothing is mentioned about the type of the Grammar, It, by default, should be taken as A Valid Grammar i.e. Type 0 Grammar which itself covers All the Grammars. 

So, Now the given problem is nothing but  "Equivalence of two RE languages" Problem.  Which is Undecidable.
