Correct Answer (Detailed Explanation is Below)
A.
0001 0010
Detailed Explanation
Correct Answer: (A) 0001 0010 7 + 5 = 12. In BCD, 12 is represented as 0001 0010. First add 0111 + 0101 = 1100. Since 1100 is greater than 1001, add correction 0110: 1100 + 0110 = 1 0010. The result is 0001 0010 in BCD.
