6) 0101 (option b)

7)0110 (option a)

8) E (optiond)

Explanation:

  6) 1's complement of the given number, change all 0's to 1 and all 1's to 0. So, the 1's complement of the number 1010 is 0101.

  7) 1's complement of the given number, change all 0's to 1 and all 1's to 0. So, the 1's complement of the number 1010 is 0101. Now add one of the LSB of this number, i.e., (0101)+1=0110.

8)The numbers 0 to 9 are still used as in the original decimal system, but the numbers from 10 to 15 are now represented by capital letters of the alphabet from A to F inclusive and the relationship between decimal, binary and hexadecimal.
