Yeas, right @Kristel.

9E = 158 = 1001 1110.

Since it is already an odd,

There will be no adding 1's.

While calculating the sum exclude the Parity bit and write down remaining bits.

ie. 10011110 = 0011110 = 30.

9E = 1001 1110.

Since it is already an odd,
There will be no adding 1's.

10011110 = 158.

Correct me if im wrong.

@Kristel.

I think you are right, I too have some doubt about this answer.
9*(16^1)+14(16^0)=158.

Someone please explain for the above answer.

What does Odd Parity mean?

In asynchronous communication systems, odd parity refers to parity checking modes, where each set of transmitted bits has an odd number of bits. If the total number of ones in the data plus the parity bit is an odd number of ones, it is called odd parity. If the data already has an odd number of ones, the value of the added parity bit is 0, otherwise it is 1.

9E = 1001 1110.

MSB 1 odd parity bit, 0011110 is data.

So 11110 - > 30(decimal).

9E = 1001 1110
It in odd parity so we remove msb 1 after that,

= 001 1110.
= (1E)16.
= 1 * 16^1 + 14 * 16^0.
= 16 + 14.
= 30.
