WHAT SHOULD BE THE ANSWER?
-48 -23 = -71
2's complement representation of -71 = 1's complement of 71 + 1
71 = 64+4+2+1 = 01000111 ==>1's complement of 71 = 10111000
2's complement representation of -71 = 10111000+1 = 10111001
option A is right answer.
some good info about 2's complement representation https://gateoverflow.in/209179/self-doubt
Gate Fever oops b is correct they want 2's complement of result.
