Question

the population of a city increasing at compounding rate of 8% per year find the population in the year 2012 if population in the year 2012 if population in the year 2012 if population on the year 2019 was 3,50,000​

Answer 1

Answer:

The population of year 2012 is 1,54,000

Step-by-step explanation:

The years between 2012 & 2012 = 7 years

increasing compound rate = 8%

increasing compound rate of 7 years

= 8 × 7

= 56%

the difference between population of year 2019 to 2012 = 56/100 × 3,50,000

= 56 × 3,500

= 1,96,000

The population of year 2012

= the population of year 2019 - difference population between 2012 to 2019

= 3,50,000 - 1,96,000

= 1,54,000
