Let the population before two years ago be x
Given the population increases by 10%
So increase in population after one year is
100
10
×x=0.1x
So population after one year is x+0.1x=1.1x
Increase in population after another one year is
100
10
×1.1x=0.11x
So population at present is 1.1x+0.11x=1.21x
But given population at present is 3,02,500
⟹1.21x=302500
⟹x=
1.21
302500
=2,50,000
Population of city two years ago is 2,50,000
