The investigator could not get the answer even after checking the street number of next door neighbor. This gives us the clue that there are more than one case where the sum of their ages is the street number of next door neighbor. From above possibilities, only sum 13 has two cases. The case 2, 2, 9 will be more likely the case because the oldest daughter(age 9) likes dogs.
