5 departments are there-:
d1 d2 d3 d4 d5
d1 to d4 requires 20 hosts each and d5 requires 6 hosts.
these are various classes of ip addresses-:
A=>0-127=>network id=8, host id=24
B=>128-191=>nid=16,hid=16
C->192-223=>nid=24,hid=8
So how do I choose an IP address for my subnetting so that minimum loss of address space happens?
The answer is 202.53.69.0/24 with host bits of 5
