A number of girls form a singing group. All but 3 of the girls are blondes, all but 4 are brunettes, and all but 5 are redheads. How many girls are in the group?

  • math -

    x = total girls in group
    x - 3 = blonds
    x - 4 = brunettes
    x - 5 = redheads

    (x - 3) + (x - 4) + (x - 5) = x
    3x - 12 = x
    2x = 12
    x = 6

    1 redhead
    2 brunettes
    3 blond
