 Uday said: (Jan 19, 2014) Given binary number is 010111.1100 1's compliment = change 0's into 1, 1's into 0. so, 1's compliment= 101000.0011 2's compliment = 1's compliment + 1 i.e., 101000.0011 1 (+) ____________ 101000.0100 ____________ 2's compliment = 101000.0100.

 Vanlalruata Hnamte said: (Jan 25, 2014) 010111.1100 Let's convert it to 1's complement. Change 0 to, 1 to 0. So 1's complement is 101000.0011. To get the 2's complement just add 1 from the 1's complement 101000.0011 + 1 = 101000.0100. So B is the answer.
