Question

PLS SOLVE IT:)The population of a country increased by an average of 2% per year from 2000 to 2003. If the population of this country was 2 000 000 on December 31, 2003, then the population of this country on January 1, 2000, to the nearest thousand would have been
A. 1 846 000
B. 1 852 000
C. 1 000 000
D. 1 500 000​

Answer 1

Solution :-

Population of the country on Jan 1, 2000 =  P

r = 2%

Total Duration = 4 years,  :  2000, 2001, 2002, 2003

If we take the compounding of the rate of growth :

        2, 000, 000 = P (1 + 2/100)^4  = P (1.02)^4

              P =  1, 847,691

If we take the growth of the population similar to simple interest of money deposits, then :

          2, 000, 000 = P + P * 2/100 * 4

            P = 2, 000, 000 / 1.08 = 1, 851, 852

        In this case the answer is B.
