This is basically a question of variable length subnet masking.

here, 8 hist id bits are divided in the following way to get exactly 3 subnets and not 4-->

10000000

    and

00000000 , 01000000

           or  

00000000

     and

11000000 , 10000000

the subnets will have following range of ip addresses- > (0 to 127), (128 to 191),(192 to 254).

DBAs are respectively->

1) 255.255.255.127

2)255.255.255.191

3)255.255.255.254
