Question

The population of a suburb is 1600find The rate of increase in the population if the population after two years is17640
How it's come

Answer 1

Answer:

note - this problem can't be solved like this(it will be very difficult) I think u wrote 16000 as 1600.

final value=initial value(1+r/100)^t

17640=16000(1+r/100)^t

17640/16000=1+r/100)^2

1764/1600=(1+r/100)^2

(42/40)^2=(1+r/100)^2

take root on both sides so power will be cancelled

$\frac{42}{40} - 1 = \frac{r}{100} \\ \frac{2}{40} = \frac{r}{100} \\ r = \frac{100}{20 } \\ = 5$
