Conversion of (98.75)10 into binary, octal and hexadecimal number system, respectively, is:

Step 1: Convert the integer part of the decimal number into the desired number system.

To convert the integer part of the decimal number into binary, octal and hexadecimal, we perform successive division by 2, 8 and 16 respectively until the quotient becomes zero. We write down the remainders in reverse order to get the binary, octal and hexadecimal equivalent of the integer part.

- Binary: 98 ÷ 2 = 49 remainder 0, 49 ÷ 2 = 24 remainder 1, 24 ÷ 2 = 12 remainder 0, 12 ÷ 2 = 6 remainder 0, 6 ÷ 2 = 3 remainder 0, 3 ÷ 2 = 1 remainder 1, 1 ÷ 2 = 0 remainder 1. Therefore, (98)10 = (1100010)2.
- Octal: 98 ÷ 8 = 12 remainder 2, 12 ÷ 8 = 1 remainder 4, 1 ÷ 8 = 0 remainder 1. Therefore, (98)10 = (142)8.
- Hexadecimal: 98 ÷ 16 = 6 remainder 2, 6 ÷ 16 = 0 remainder 6. Therefore, (98)10 = (62)16.

Step 2: Convert the fractional part of the decimal number into the desired number system.

To convert the fractional part of the decimal number into binary, octal and hexadecimal, we perform successive multiplication by 2, 8 and 16 respectively until the fractional part becomes zero or until we get the desired precision. We write down the integer part of each multiplication as the corresponding digit of the binary, octal or hexadecimal equivalent.

- Binary: 0.75 × 2 = 1.5 → 1, 0.5 × 2 = 1.0 → 1. Therefore, (0.75)10 = (0.11)2.
- Octal: 0.75 × 8 = 6.0 → 6. Therefore, (0.75)10 = (0.6)8.
- Hexadecimal: 0.75 × 16 = 12.0 → C. Therefore, (0.75)10 = (0.C)16.

Step 3: Combine the integer and fractional parts to get the final result.

- Binary: (98.75)10 = (1100010.11)2.
- Octal: (98.75)10 = (142.6)8.
- Hexadecimal: (98.75)10 = (62.C)16.

Therefore, the correct answer is option D.

Concept:
Conversion of decimal to binary:

Step 1: Divide the number by 2 keeping notice of the quotient and the remainder. Continue dividing the quotient by 2 until you get a quotient of zero.
Step 2: Write out the remainders in the reverse order to get the equivalent binary number.
For converting decimal fractions to binary numbers, follow these steps:
For converting decimal fractions to a binary numbers, follow these steps:
Then write out the integer parts from the results of each multiplication to get the equivalent binary number.
Conversion of binary to octal:
Make pair of three binary number which forms an octal number.
Conversion of binary to hexadecimal:
Make pair of four binary number which forms a hexadecimal number.
Calculation:
Given, that the decimal number = (98.75)10 
98 / 2 = 49 with remainder 0
49 / 2 = 24 with remainder 1
24 / 2 = 12 with remainder 0
12 / 2 = 6 with remainder 0
6 / 2 = 3 with remainder 0
3 / 2 = 1 with remainder 1
1 / 2 = 0 with remainder 1
Write in reverse order:
98 = 1100010
0.75 × 2 = 1 + 0.5
0.5 × 2 = 1 + 0
.75 = .11
(98.75)10 = (1100010.11)2 
(98.75)10 = (001  100  010.  110)2 = (142.6)8 ...........(from table 1)
(98.75)10 = (0110  0010.  1100)2 = (62.C)16...........(from table 2)
