The population of the town 3 years ago was 'b' and the population of the town for next 3 years fro now will be 'c'.what is the current population of the town i the growth rate is same?
a)square root of bc
b)b square root of c
c)c square root of b
d)b square root of(b/c)
e)square root of b/c

• a) square root of bc
  
  Late the population increases at the rate of r per year and present population is x, then
  b[1+(r/100)]^3 = x =>[1+(r/100)]^3 = x/b
  Also x[1+(r/100)]^3=c => x*x/b= c or x^2= bc
  Hence x= Sqrt(bc)

• From that Late the population increases at the rate of r per year and present population is x, then
  b[1+(r/100)]^3 = x =>[1+(r/100)]^3 = x/b
  Also x[1+(r/100)]^3=c => x*x/b= c or x^2= bc
  Hence x= Sqrt(bc)
