The present population of a district is 325000. If it rises to 572761 during next 5 years, then find uniform rate of growth in population.

OPtion

1) 10.5
2) 11.0
3) 11.5
4) 12.33
5) 12.5
6) 12.0
7) 13.33
8) 13.0
9) 13.5
10) None of these

Solution

Population after n years = P[1+R/100]^n
=> 572761 = 325000 [1+R/100]^5
=> 1.762342 = [1+R/100]^5
=> [1+R/100] = 1.12
=> R = 12%
