These are the KHB rules for allotment:
KHB has the following Percentages of Reservation for allotment of its
properties.
18% of its properties are reserved for Scheduled Castes and
Scheduled Tribes,
15% for State Government,
5% for Central Government,
5% for Defense,
5% for Senior Citizens (in all Categories)
3% for the Physically Handicapped
and 49 % for others
So for general, 10000 sites = 1200 acres minimum
If 780 were acquired, 5000 sites possible
2500 for general
Chances in general become 1 in 6
