Show answer & explanation
Correct answer: D
Decimal 512 equals 2^9, which is binary 1000000000 containing a single one. Thus, (A) matches with (III).
One Kilobyte equals 2^10 bytes or 2^13 bits, making x equal to 13. Thus, (B) matches with (I).
Hexadecimal A plus B equals 10 plus 11, resulting in decimal 21 or hex 15. Thus, (C) matches with (IV).
Binary 00010100 converts to decimal 20. Thus, (D) matches with (II).
