Question

Quizplus · Accepted Answer

To perform the indicated operation, we need to add the hexadecimal numbers given. Adding the 4th digit of each number, we get:

7 + f + e + b = 2a (and a carry of 2)
Adding the 3rd digit along with the carry:

c + 7 + 7 + 8 + 2 = 28 (and a carry of 2)
Adding the 2nd digit along with the carry:

1 + 4 + 8 + b + f = 2c (and a carry of 2)
Adding the 1st digit along with the final carry:

1 + 7 + b + 8 + 1 + 2 = 1e

Therefore, the result is 1e2c282a, which corresponds to choice B.
