HI,
u would have seen this weird formula in organisms n populations chapter n ie
Nt= No * ert
where
r is the
intrinsic rate of natural increase and
t- time period
r can be calculated as follows r=b-d
ie 
birthrate – death rate
in this q 
b=0.028
d= 0.008 , therefore b-d=.020
Nt = 14 million * e.020 * 10(by the way the time period is 10 years ie from 2005-2010)
plug in the values and after solving you will get
Nt=17 million
 
HOPE THIS HELPS
