The population of a city increases @ 4% p.a. There is an additional annual increase of 4% of the population due to the influx of job seekers, find the % increase in population after 2 years ?

• Say you start with P people. In 1 year you have 1.08P people. In 2 years
  there are 1.08(1.08P) people = 1.1664P people.
  
  The increase is 1.1664P-P = 0.1664P
  The rate of increase = 0.1664P/P=.1664 = 16.64%

• total annual increament in population = 4+4 = 8%
  let the population be x
  Population after 2 years = 1.08x +.0864x
  Population increase = 1.08x + .0864x - x
  %increase = ((1.08x + .0864x - x)/x )*100
  = ( 1.08 + .0864 - 1 )*100
  =.1664*100
  =16.64%

• 1 year increment =4+4=8%
  required %increment= 8+8+8*8/100 =16.64%
• 7 years agoHelpfull: Yes(9) No(0)
• let population now be 100
  as given population increased 4% p.a.
  therefore population will be 104 after one year
  and also given additional increment in population due to job seekers is 4%
  therefore population will be =104+104X0.04
  =104+4.16
  =108.16
  after one year, population is 108 (4% + 4%)
  
  after 2 years, population is (.04*108.16)+108.16 = 112.4864
  due to job seekers population will be after two years=116.986256
  increase in population = 116.986256 - 100 = 16.986256
  
  % increase = (16.986256/100) * 100 = 116.986256%

• so for a total 8% p.a the population increases
  so 16% increase after the 2 years
• 12 years agoHelpfull: Yes(7) No(13)
• let the population be x.... (x(1+ 8/100)^2 - x)/x *100 =16.64%
• 9 years agoHelpfull: Yes(2) No(1)
• 4%+4%=8% for 1 year
  so % increases after 2 years 2*8 =16%
• 7 years agoHelpfull: Yes(0) No(2)
• use effective percentage formula....
  per year population is increasing 4%+4% = 8%
  
  1year 2year
  8% 8%
  
  effective % = 8 + 8 + 8*8/100
  = 16+64/100
  = 16.64%

• simply, apply
  a+b+(a*b)/100
  where, a=b=8(total percent of increase of population p.a)
