Can somebody please explain how to solve using 1's complement in detail?

In question, they have said that it is a signed number so no need to search for a sign as we know that sign bit is placed as MOST SIGNIFICANT BIT so just reverse bits 0 to 1 and 1 to 0 or just subtract the whole binary bit with all 1's then you will get 00001011 whose value is 11.
Since the MSB is 0 given decimal equivalent is positive.
Since the MSB is 0 given decimal equivalent is positive.

The MSB (Most Significant Bit) is 1, so this is a negative number in 1’s complement. , 11110100 (in 1’s complement) = -11 (decimal).
