Hexadecimal code is also called 8-4-2-1 code.

So that 10 is addition of 8 & 2 so this place value only high.

So answer is 1010.

Similarly for any other value like 13 so that addition on 8 & 4& 1 is 13 so this place value is high so answer is 1101.

Use the code:

8421

We can write 10 as 8+2 from these numbers.

So,put 1 in the places of 8 and 2

and 0's in the places of remaining.

now it becomes,1010.

I.e., option (b).

It is the final answer.

Also 8+2 = 10,1000+0010 = 1010.

Similarly 8+5 = 13, So, 1000+0101 = 1101.

Similarly 8+5 = 13, So, 1000+0101 = 1101.

10/2 = 5, cry = 0.

5/2 = 2, cry = 1.

2/2 = 1, cry = 0.

So answer is 1010.

5/2 = 2, cry = 1.

2/2 = 1, cry = 0.

So answer is 1010.

Also 9+5 = 14, 1001+0101.

Similarly 9+9 = 18. So, 1001 = 1001.

Similarly 9+9 = 18. So, 1001 = 1001.
