I guess you are asking that from 8 to 13 , MSB is 1 and why we considered numbers with 1 as MSB unsigned. The number if it is signed is represented in 2's complement form . In the question it is given that we have to consider unsigned representation only.

Eg:

+12 is represented as 1100  <<= We have to consider this according to question (this is unsigned representation)

-12 is represented as 10100

Are you clear now?
