ANS:C - 00110010

49 = 00110001,
1 = 00000001,
49 + 1 = 00110001 + 00000001 = 00110010.

ANS:B - 11010000101000

Given 3428

Follow the rule 8421.
According to that;
3 = 0011.
4=0100.
2= 0010.
8= 1000.

By combining these binary digits we get 0011010000101000. By eliminating the first 2 zeros we get 11010000101000.

ANS:D - 1476

5238 convert from decimal to binary. So, the Answer would be 1010001110110. Start from the last which is 0 count 4 backwards (4 bits), regroup it so its easier. It will look like this 0001 0100 0111 0110 ( I added 4 zeros in front-doesn't matter actually just for formality). Those grouped bits convert from binary to decimal to get the answer which is 1476.

ANS:B - False

This case is valid for excess-3 code.

Not for gray code.

ANS:B - False

Conversion of one number system to another number system is called that particular conversion.

Here equivalent weight is calculated of that decimal number.

ANS:A - True

In mathematical numeral systems, the base or radix for the simplest case is the number of unique digits, including zero, that a positional numeral system uses to represent numbers. For example, for the decimal system (the most common system in use today) the radix is ten, because it uses the ten digits from 0 through 9. In any numeral system, the base is written as "10". In a base ten numeral system, "10" represents the number ten; in a base two system, "10" represents the number two.
