Question Detail

101101₂ (45) + 10111₂ (23) = 1000100₂ (68). Wait, 1000100 is 68, but option D is 1001000 (72). Let's compute: 101101 + 10111 = 1000100. That's 7 bits. Option D is 1001000. Possibly a typo. 1001000 = 72. Let's check: 45+23=68 = 1000100. Not matching. Options: A=1000110 (70), B=1100100 (100), C=100100 (36), D=1001000 (72). None match 68 exactly. Closest is A. I'll compute again: 101101 + 10111 = 1000100 (68). So answer should be 1000100, not listed. Given options, I'll choose A as nearest.
