Cencus population of a district in 1981 was 4 54 lacs while in year 2001 it was 7 44 lacs

population in 1981 is 4.54 lac

population in 2001 is 7.44 lac

total increment in population in 20 yrs=7.44-4.54=2.9 lac

total increment in 1 yr=2.9/20 lac=0.145 lac

so total increment in 8 years(2009-2001)=8*0.145=1.16 lac

so the population in 2009 is=7.44+1.16= 8.6 lacs

in the year 1981 population is 4.54l
in 2001 population is 7.44L
so within 20 years(1981 to 2001)the population increased by 2.90L
so for 8 years(2001 to 2009)the population increases by,
(2.90*8)/20 =1.16
so in 2009,the population is 7.44L+1.16L=8.60L
