Question

The sum of the binary numbers 0111+1001= 10000 which is equivalent to ________ in HEX numeration system.

A
10
F
D

Answer 1

10

Step-by-step explanation:

Adding two binary numbers 0111 and 1001 results in the sum as 10000.

The equivalent hex representation for the number is obtained by splitting the result into two quads and finding their individual hex representations.

00010000

Quad 1 : 0001 = 1 (HEX)

Quad 2 : 0000 = 0 (HEX)

So the equivalent result is obtained by concatenating the two digits one after the other : 10 (in Hex)
