Each of my sons has as many brothers as sisters, but each of my daughters has only half as many sisters as brothers.
How many children do i have?

  • Algebra - ,

    #Sons = s, #Daughters = d

    s-1 = d

    d-1 = s/2

    ------->

    s = 4

    d = 3

    I certainly don't have an equation for this, but I believe there would be 7 children....4 boys and 3 girls. That would mean each boy has 3 brothers and 3 sisters and each girl has 4 brothers and 2 sisters.

  • Algebra - ,

    #sons = h #daughters = d brothers = b sisters = s

    h = b+s
    d = h/2

    so if you have one daughter you have two sons and so on so forth because the daughters only equal half of the sons.
