The number of POS centres in rural areas of Kerala in year 2017 = 60

The number of POS centres in rural areas of Kerala in year 2018

=60(1+25/100)^1=75

The number of POS centres in semi-urban areas of Kerala in year 2017 = 10

The number of POS centres in semi-urban areas of Kerala in year 2018

For Sikkim =460/20=46/2

For Telegana =620/20=62/2

For Tamil nadu =1750/(210+ 20)=175/23

For Kerala =60/10=6
