Answer: Option A

Solution (By Examveda Team)

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.

    3fh
    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
