Question

the population of a country was 55 crores in 2005 and is growing at 2% p.a C.I , the population in the year 5015 is estimated as ?
a)5705
b)6005
c)6700

Answer 1

in the year 2015***

Answer 2

Shall I assume that 2% p.a C.I means
2% per annum compounded instantaneously ?

the amount = 55 e^.02t
if 2005 ---> t = 0
then 2015 --- t = 10

amount = 55 e^(.02(10))
= 67.177 crores

(is 1 crore equal to 10 million?
I see one answer as 6700, but that would not match your units.)

Answer 3
