It is observed that the population of a city increase at the rate of per annum.
It is observed that the population of a city increase at the rate of \( 8 \% \) per annum. If the present population of the city is \( 125000, \) then the population of the city after 2 years will be
- A. 145000
- B. 145800
- C. 154000
- D. 154800
Step-by-step solution
Population after n years = P(1 + r/100)^n. Here P=125000, r=8%, n=2. So after 2 years = 125000*(1.08)^2 = 125000*1.1664 = 145800.
