Option 4 is ans.

By option elimination

As they asked minimum take first  if no. of family is 2

Now try to Satisfy given constraint

Adult > Boy > Girl > Family

5>4>3>2 (We need this but the constraint each family is atmost 2 adults not holds here)

So now suppose  if no. of family is 3

Now try to Satisfy given constraint

Adult > Boy > Girl > Family

6>5>4>3

Now 3 families each have 2 asults so total 6 Adults.

Each family 3 children so total 9 children (5Boys + 4 Girls)

So all condition satisfied with No. Of family =3

 

So Option 4 is Ans.
