Question

Population of a city increases by 10% in 1st year, it increases by 20% in next year. If initial population in 10,000. Calculate the population after two years.

Answer 1

Answer:

Initial population = 10,000

Population increased in the first year =10%

10,000*10/100= 1,000

=10,000+1,000

=11,000

Population increased in the second year=20%

=11,000*20/100=22,000

=11,000+22,000

=33,000

33,000 is the total population of the city
