Question

the population of city increased by 10% annually if the present population is 65 000 what will be the population 2 year ago​

Answer 1

Answer:

78650

Step-by-step explanation:

Since, the population is,

A = P(1+r)$(1+r)^{l}$$l$

P = initial population,

r = rate of increasing per period,

t = number of periods,

Here, P = 65000, r = 10% = 0.1, t = 2,

Hence, the population after 2 years would be,

= 78650
