**Explanation:** Here, we have

A = 1111 1010 = – 6_{10} (A is a 2’s complement number)

B = 0000 1010 = 10_{10} (B is a 2’s complement number)

A x B = – 60_{10} = 1 011 1100_{2} = 1 100 0011 (1’s complement) = 1 100 0100 (2’s complement)

Thus, the product of A and B in 2’s complement is 1100 0100, which is option A.

So, A is the correct option

for this question wht I did first,simply multiply both numbers and the result which I got 000100111000100

after taking 2's complement of this -2500 came.plz someone verify this.

I long it is taking long time but I want to know my mistake [email protected] @debashish

There are sequence of 1's in left side delete all consecutive 1's except last one i.e;(delete four 1's from starting) This is shortcut of finding a decimal number from 2's compliment form

First write +60 in binary (using 8 bit because here all options are in 8 bits)

+60 in binary=00111100
