the population of the village increase in 10 year is 5%
so population increase in 1 year is 5/10=1/2 or 0.5%
then increase in 20 year in percent = 20×0.5%=10%
the current population is 8820
so the 10 % of the population is=8820×10/100=882
so the population after 20 year =8820+882
=9702
hence the population after 20 year is 9702
I hope it is correct
thank you
