NIMCET 2017 Question Paper with solutions

${\left(147\right)}_{10}$ convert into ${(?)}_2$
${\left(147\right)}_{10}$ = ${\left(10010011\right)}_2$
First bit (the left most) indicates the sign,
1= negative, 0= positive
Positive binary computer representation on 12-bit if needed, add extra 0ft in front of the base 2 number :
For l's complement' replace all the bits on 0 with Is and all the bits set on 1 with 0s.
Vs complement of
(-147) = 111101101100
For 2's complement, add 1 to the number of l’s complement. 2.s complement of (-147)
111101101100+1=111101101101
