the population of a country is increased by 2% in one year and 3% in next year.what is the combined growth of population in these two year

• concept of successive percentage, total percentage= x+y+xy/100
  put x=2 and y=3
  combined growth= 2+3+2*3/100
  = 5+0.06= 5.06%

• let initially population is 100%.
  therefore 100%---2%increase---102%-----3%increase---(102+3% of 102 )
  =102+(3/100)*102
  =105.06
  therefore 105.06-100=5.06% is the answer

• the population of a country is increased by 2% in one year and 3% in next year.
  The combined growth of population in these two years = (1.02*1.03 -1.0)*100 percent = 5.06%

• let initial population 100
  1st year it increased by 2% that equals to === 102 ok (how? 2% of 100=2 right )
  now next year increased by
  3% i.e= 3.06 (how? 1% of 102 = 1.02 so 3% =3 * 1.02 = 3.06 )add it
  
  102 + 3.06 =105.06
  so for 100 after 2 year its 105.06
  i.e 5.06% increased

• let the population be 100 after 1 year it will become 102 and after 3 yr it will become 102+(3*102/100).so it becomes 105.06.so total increase in population is 105.06-100=5.06

• 5.06%
  
  taking x as the start
  after first year it is 1.02x
  after second year it is 1.03*1.02 = 1.0506x
  total increase = 5.06x = 5.06%

• let the initial population be 100
  after 1st year
  100+2% of 100 = 102
  after the second year
  102 + 3% of 102 = 105.06
  
  the combined percentage can be found by
  
  105.06 - 100 = 5.06
  then
  (5.06/100)*100 = 5.06%

• 1.02*.102=1.0506
  so answer is 5.06%

• put x=2 and y=3
  apply x+y+xy/100
  combined growth= 2+3+2*3/100
  = 5+0.06= 5.06%

• let initial be 100 .then after one year 102.
  3 per of 102 is 3.06
  overall is 2+3.02=5.06.which is combined growth of population.

• ans is 5.06%
  a=2, b=3 for successive percentage using formula is a+b+ab/100
