no ans given as 0xAB

Above answer is with the parity bits + message included. But for message answer will be 0xAB.

1	2	3	4	5	6	7	8	9	10	11	12
1	1	1	0	0	1	0	1	1	1	1	1
P1(parity)	P2	M1(message)	P3	m2	m3	m4	P4	m5	m6	m7	m8

Now, I'm taking the even parity.

P1 = { 1,3,5,7,9,11} =  1 1 0 0 1 1 ( EVEN)

P2 ={2,3,6,7,10,11} = 1 1 1 0 1 1 ( ODD)

P3 = {4,5,6,7,12}  =    0 0 1 0 1 ( EVEN)

P4 = {8,9,10,11,12} =  1 1 1 1 1 ( ODD)

C4 C3 C2 C1

1      0      1     0   = ( 10th bit position have to be change)

then message with parity will be ==> 0xE5B.

Message = 0xAB.

should be 0xE5B
