    Answer (4)3

    Families = 3
    Girls = 4
    Boys = 5
    Adults = 6

    So, There are 3 families with 2 adults and 3 children in each family.

    Dear TSK,
    your answer is very true.If we go with the minimum of the answer options ie., 2, families=2 => girls=3 => boys=4 => adults=5, this contradicts the "at most count of 2 adults per family".
    The next minimum value 3 satisfies all the conditions.
