Dear student
 
in the beginning of 2016 = 8000 + 8000*5/100 = 8400
Now 1600 people migrated, hence remaining = 8400 – 1600 = 6800
now at the end of 2017 = 6800 + 6800*5/100 = 7140

Population in the year 2015 = 8000
Population rate growth = 5% 
So, in 2016 popultion should be 8000+ 8000*5/100 = 8400
Remaining people after migration = 8400-1600 = 6800 
5% populaton will increase at the end of 2017 
6800+ 6800*5/100 = 7140 would be correct ans
