Question

Population of a village increases by 10% per year. Find the total population after 3 years if present population is 1000.

Answer 1

present population of the village = 1000
percentage of the population increase per year = 10% of 1000
= 100
therefore the increase in population in 3
year = 300
show the total population of the three year of the village = 1000 + 300
= 1300

Answer 2

increase of population in 3years= 30per.
present Population= 1000
so, 30per. of 1000=
30/100×1000=300
300+1000=
1300
Population after 3 years will be 1300.
