Then on solving the output of 3rd gate you will get (B'D' + BD). Try this Then reply we both will cry together 0 votes 0 votes Nandkishor3939 commented Feb 4, 2019 reply Follow Share I also gave 4 as answer : viz wrong because it the question it was mentioned that complement is provided already ... i.e. we dont have to use 1 nor gate: so 4-1 =3 0 votes 0 votes Mounikap commented Feb 4, 2019 reply Follow Share The complement is only for input s.i.e. complements of a,b,c,d....so that we need not to use extra gates for complemented form of inputs 0 votes 0 votes Nandkishor3939 commented Feb 4, 2019 reply Follow Share Its fine to make such mistakes .... it happens due to time constraint 0 votes 0 votes jain2986 commented Feb 4, 2019 reply Follow Share Correct Answer should be 4.
