Add the two numbers 87H and 79H in the 8085 microprocessors, then
Add the two numbers 87H and 79H in the 8085 microprocessors, then
Show Hint
In binary addition, if there is a carry out of the most significant bit, the carry flag is set to 1. If the result is zero, the zero flag is set.
Updated On: May 5, 2025
- Carry flag = 0 and zero flag = 0
- Carry flag = 0 and zero flag = 1
- Carry flag = 1 and zero flag = 0
- Carry flag = 1 and zero flag = 1

The Correct Option is C
Solution and Explanation
When adding the two hexadecimal numbers 87H and 79H, the result is 100H. The carry flag is set to 1 because the result exceeds the maximum value that can be stored in an 8-bit register (FFH). The zero flag is 0 because the result is non-zero.
