Question

in a state, the poverty rate was formed found to decline by 2% per year. If 30,000 people were found poor in a year. find how many poor people would be less after 2 years?

Answer 1

at end of first year,
2% of 30000 = 600
poverty reduces by 600
so 30000-600 = 29400
at end of second year,
2% of 29400 = 588
so 29400-588 = 28812
30000-28812 = 1188
1188 people would be less after 2 year

Answer 2

Total number of people=30,000
after one year,
30,000*2/100=600
30,000-600=29,400
After the next year,
29,400*2/100=588
29,400-588=28812.
30,000-28812=1188.
Therefore 1188 poor people would be less.
