a rate of 9% every year. What was the
population of the city 2 years ago, if

Answer 1

Answer:

present population=28,00,000

Calculate CI on Present population

28,00,000×9×1/100=252000

Subtrat the SI From present population

2800000-25200=2774800

now take the SI again

2774800×9×1/100=249,732

Subtract the Sec SI

2774800-249,732

=2525068
