How many floors does the building have (including ground floor)?I. The...
From I : Suppose 1 family stays on ground floor, then the other should be on 2nd floor, and then third family on 4th floor, or there can be any other arrangement such no two families are on adjacent floors.
From II : Maximum of 4 floors means that the building can have 0 or 1 or 2 or 3 or 4 floors.
But if both statements are combined, which says that there are 3 families and they do not stay on alternate floors and maximum can be 4 floors, it is predicted that there are 4 floors in this building

How many floors does the building have (including ground floor)?I. The...
Statement I: There are 3 families in the building and no two families live immediately above or below each other.
This statement alone does not provide any information about the number of floors in the building. It only tells us that the three families do not live immediately above or below each other, but it does not give any indication of the total number of floors.
Statement II: The area in which building is built has a rule that a building cannot have more than 4 floors (including ground floor).
This statement alone tells us that the building cannot have more than 4 floors, including the ground floor. However, it does not provide any specific information about the number of floors in this particular building.
Combined statements:
By combining the information from both statements, we can determine the number of floors in the building.
Since the area has a rule that a building cannot have more than 4 floors, and there are 3 families living in the building, it means that each family must occupy one floor.
Therefore, the building must have at least 3 floors, including the ground floor, in order to accommodate each family on a separate floor. Additionally, since the building cannot have more than 4 floors, we can conclude that the building has exactly 3 floors.
Hence, the data given in both statements I and II together are necessary to answer the question.
Therefore, the correct answer is option E.
