Q-43 Paper-III (Computer Sc.) has two correct answers UGC NET 2012
Dear Sir,
My roll no is 17873204 (OBC category) is failing by one mark but this is due to mistake of UGC NET.
Here with I am giving details, pls tell me what should I do
For question number 43 there are two correct options (B) and (D) but in your answer key (UGC NET) it is shown only (D). I opted (B). Here I am giving the proof.
Answer (D)= a*b(b*+aa*b)* = a*b((b*)*+(aa*b)*)* (By using (P+Q)*=(P*+Q*)*)
= a*b(b*+(aa*b)*)* (By using (R*)*=R*)
=a*b(b+(aa*b))* (By using (P+Q)*=(P*+Q*)*)
=a*b(b+aa*b)*
= Answer (B) It means both are equivalent so they will generate same language which is generated by Finite State Machine. It can be verified by any expert.
Regards
om pal
