Detailed explanation-1: -Statement I: Minimum number of bits required to store any 3-digit decimal number is 10. Explanation: To calculate the number of possibilities given the number of digits: possibilities = base. So, if you have 3 digits in decimal (base 10) you have 103 = 1000 possibilities.
Detailed explanation-2: -Q2: How many bits does it take to represent a decimal digit? A2: You need at least 4 bits to represent all decimal digits.
Detailed explanation-3: -The third decimal digit from the decimal point is the thousandths digit. For example, 0.008 is eight thousandths. Read the whole set of three decimal digits as a number, and say “thousandths.” 0.825 has 8 tenths, 2 hundredths, and 5 thousandths.
Detailed explanation-4: -Statement II: Minimum number of bits required to store the largest 2-digit decimal number is 7.
Detailed explanation-5: -For example, a string of three bits can represent up to eight distinct values as illustrated in Table 1.
