The population of a city in the year 2014 is 1,80,000 and increases at a rate of 20% per year.
Find the population of the city in the year 2016?
2,40,000
2,59,200
2,55,000
2,54,300
Explanation:
The population of a city in the year 2014=1,80,000
Increasing rate in per year=20%
so,the population of the year 2015 =population of 2014 +20%of population of the year 2014
=1,80,000+$(1,80,000\times\dfrac{20}{100})$
=1,80,000+36,000
=2,16,000
then the population of the year 2016=population of 2015+20% of population of the year 2015
=2,16,000+$(2,16,000\times\dfrac{20}{100})$
=2,16,000+43,200
=2,59,200
