We found 7 errors in the ans key of PSC.(4-D,10-C,11-C,14-D,21-B,27-C,31-A)We are going to sent these errors to PSC in the prescribed format. Otherwise it will not be considered. will you?

Qn.2 A multiplexer is often used with a complementory demultiplxer on the receiving end.
So there need both MUX and DEMUX for for sharing system resources among multiple users.
so the answer is - A or B
=C'D'B+CD'B since A+A'=1

Qn.34 To find postfix
