Answer 1

Answer:

increase in population per years=5%

total population=16000

5%of 16000=800

increase in population after 2years 2*800 =1600

population after 2years = 16000+1600=17600

Answer 2

Answer:

Population of a town increases per annum = 5%

Present population = 16000

1st Year = 5÷100×16000 =800

16000+800 = 16800

2nd Year = 5÷100×16800= 840

16800+840 = 17640
