In question above we understood that positive number and unsigned is represented same as in 2's complement.

here in question below the hex number is unsigned because sign digit for Hex is F(15)so it will be same in F's complement then the options are wrong.

F's complement of (2BFD)hex is

(a) E304

(c) D402

(b) D403

(d) C403

Similarly below question complimented answer will be same as number given is positive(bcoz msb is not 7).

Determine 8's compliment of an octal number 2670?

Right??
