Question

the population of a town increases at the rate of 40 per thousand it population after two years will be 6084 find it present population.​

Answer 1

Answer:

5625

Step-by-step explanation:

Let, present popation is P

increase rate (r)=4%

time (n)= 2 yrs

after 2 yrs the population will be 6084

so,

P(1+r/100)^n = 6084

or, P(1+4/100)² = 6084

or, P(104/100)² = 6084

or, P(26/25)² = 6084

or, P = (6084×25×25)/(26×26)

so P = 5625
