Question

population of a country was 55 crore in 2005 and is growing at 2% C.I.the population in the year 2015 is

Answer 1

t=2015-2005
=10
r=2%
p=550,000,000
Let the total population be A
A=P(1+(r/100))^10
=550000000*(1.02)^10
=550000000*1.21899441999
=670446930.995

Answer 2

Answer: There will be 67 crores of population in the year 2015.

Step-by-step explanation:

Since we have given that

Initial population in 2005 = 55 crores

Rate of growth = 2%

We need to find the number of population in the year 2015.

So, n = 10 yrs

So, According to question, it becomes

$Amount=P(1+\frac{r}{100})^n\\\\A=55(1+0.02)^{10}\\\\A=55(1.02)^{10}\\\\A=67.044\\\\A\approx 67\ crores$

Hence, there will be 67 crores of population in the year 2015.
