100

r

)

t

where Z is population at the end of duration

A is present population

t is tme perior

r is rate of interest

we know that 4.7% =0.047

putting the values

Z=6809000+(1+

100

4.7

)

4

Z=6809000(1.047)

4

Z=6809000×1.2016741717

Z=8182199

Thus population at the end of 2015 will be 8182199
