Address 200H contains the byte 3FH. What is the decimal equivalent of 3FH
Answer & Solution
Correct Answer:
Option
A
To convert a hexadecimal number to its decimal equivalent, you need to understand the place values in hexadecimal.
In hexadecimal, the digit positions represent powers of 16, starting from 16^0 on the right.
The number 3F in hexadecimal can be broken down as follows:
3 is in the 16^1 position, so its value is 3 * 16 = 48.
F is in the 16^0 position. In hexadecimal, F equals 15, so its value is 15 * 1 = 15.
Adding these values together gives 48 + 15 = 63.
Therefore, the decimal equivalent of 3FH is 63.

H=here H is hexadecimal
2⁵ + 2⁴ + 2³ + 2² + 2¹ + 2⁰
32+16+8+4+2+1=63
0011 1111
2⁵ + 2⁴ + 2³ + 2² + 2¹ + 2⁰
32+16+8+4+2+1=63
3=11
F=15=1111
3f= (11)(1111) now convert into decimal
111111= 1*2^5+ 1*2^4+ 1*2^3+ 1*2^2+ 1*2^1+ 1*2^0= 32+16+8+4+2+1= 63
