@Ashok.
In binary representation 5 is 101.
So, complementing the bits we have 010 i.e. 2.

Just change the 1 with 0 and 0 with 1.
1-->0
0-->1
So, 10-->01.
1-->0
0-->1
So, 10-->01.

1's complement :
It is obtained by changing all 1's to 0's and al 0's to 1's.
Example : 0110.
It's 1's complement is 1001.

@Gopal.
For 2's complement, we first find 1's complement and then add 1 in that number.
Eg:
We have a binary number 0111,
2's complement = [1's complememt] + 1 .
1's complement = 1000,
now add 1,
1000
+ 1
===========
1001
