In BCD encoding system, 25, will be represented as?
Answer Details
In BCD (Binary Coded Decimal) encoding system, 25 will be represented as 00100101.
BCD is a system that represents each digit of a decimal number with its equivalent binary code. In BCD, each decimal digit is represented by a four-bit binary code. Therefore, the decimal number 25 is represented in BCD as follows:
The binary representation of 2 is 0010, and the binary representation of 5 is 0101.
So, combining the binary codes for both digits, we get 0010 0101, which is equivalent to the decimal number 25 in BCD representation.
Therefore, the correct option is 00100101.
