Question

At present the population of a village is p and if increase rate of population per year be 2r%, the population will be after n years

Answer 1

Answer:

p(1+r/50)^n

Step-by-step explanation:

p(1+2r/100)^n=p(1+r/50)^n

Answer 2

Population after n year = P ( 1 + $\frac{r}{100}$ )ⁿ

P = present population,

r% =rate of increase population in per year.

n = number of years.

r% = 2r% (given)

∴Population after n year = P ( 1 + $\frac{2r}{100}$ )ⁿ

                                          = P (1 + $\frac{r}{50}$ )ⁿ

Ans :-Population after n year will be P ( 1 + $\frac{r}{50}$ )ⁿ
