Question

14. The population of a town increases 5%
annually. If its present population is 84000what will be thepopulation in 2 years?​

Answer 1

Answer:

92,610

Step-by-step explanation:

5% of 84000 is 4200

Then the population becomes 84000+4200

88200

Then for next year

5% of 88200 is 4410

Therefore the total is 88200+4410 =92610

Answer 2

Answer:

92,610

Step-by-step explanation:

Given :

present population = 84000

rate of increase = 5%

so in the next year (i.e. after 1 yr)

population  = 84000 + (84000×$\frac{5}{100}$)

= 84000 + 840×5

= 84000 + 4200

= 88200

after 2 years

population = 88200 +(88200 × 5 100)

= 88200 + 4410

= 92610
