Out on my street, there are a certain number of pigeons sitting on telephone poles. If there were exactly 2 pigeons sitting on each telephone pole, then 1 pigeon would have no space to sit on. If there were exactly 3 pigeons sitting on each telephone pole, then there would be 1 telephone pole with no pigeons on. How many pigeons were there?

    If there were exactly 2 pigeons sitting on each telephone pole, then 1 pigeon would have no space ....the number of pigeons is odd. And, numberpigions=numberpoles*2+1

    TIf there were exactly 3 pigeons sitting on each telephone pole, then there would be 1 telephone pole with no pigeons on...means 3*poles-1=number pigeosn

    Pig=2Poles+1
    Pig=3Poles-1

    subtract equation 1 from 2
    0=poles-2 or poles=2
    pigeons=5

  • Algebra - ,

    Pi=2Po+1,
    Pi=3(Po+1)
    after solving we get the result as
    Pi=9
    and
    Po=4
