Which represents decimal 59 in BCD (binary-coded decimal)?

  1. A0011 1011
  2. B0101 1010
  3. C0101 1001
Show answer and explanation

Answer: C. 0101 1001

In BCD, each decimal digit is represented by its own 4-bit binary number. 5 is 0101 and 9 is 1001, so 59 is 0101 1001. 0011 1011 is 59 in ordinary binary.
