Question

the population of a town was 1200 after two years the population was found to be 1400 find the average percentage increase per year​

Answer 1

Answer:

8.33 %

Step-by-step explanation:

Initial population = 1200

population after 2 years = 1400

so, increase in population after 2 years = initial population -current population

=  1400 - 1200 = 200

Now if the population increased by 200 in 2 years, so we can say that it increases 100 annually.

Now, increase in % population  = $\frac{\textrm {increase in population}}{\textrm{initial population}}   \times 100$  %

= $\frac{100}{1200}   \times 100$ %

= 8.33 %
