Ok here is the problem: A hostess said to Mrs. Raines " I have three sons, the product of there ages is 72, the sum of there ages is my house number." ( it desnt give the house number.) Then it says that mrs. Raines needed more info. THe hostess then told her that her eldest son loves pecan pie. With that Mrs. Raines told their ages.

  • math -

    excuse me but my english is so bad

    72=2*2*18 (sum 22)
    72=2*3*12 (sum 17)
    72=2*4*9 (sum 15)
    72=2*6*6 (sum 14)
    72=3*3*8 (sum 14)
    72=3*4*6 (sum 13)

    due to the fact mrs raines needed more info, only "2*6*6" and "3*3*8" are posible.
    "her eldest son" means "no twins"
    so the solution is 8,3,3
