Answer:
Population village 3000
% of increase in population :10%
Increase in population -(10/100)x3000
=300
New population-3000+300=3300
Now % of decrease in population-10%
Decrease in population- 10/100x3300
=330
Now new population 3300-330
=2970
Difference in population=3000-2970
=30
Decrease in population=30/3000x100
1
Therefore decrease in population is 1%
