The population of a town is 1,76,400 . If it increases at the rate of 5% per year, what will be its population 2 years hence ? What was it 2 years ago ?	Choices.
A) 140000	B) 180000	C) 160000	D) 200000	E) None of them
Population after 2 years = 176400*[1+(5/100)]^2   =[176400*(21/20)*(21/40)]   = 194481.   Population 2 years ago = 176400/[1+(5/100)]^2   =[716400*(20/21)*(20/21)]= 160000.   Answer is 160000.
