I don't think I understand the question. I assume it's asking "how many of the ladders available to him do not have two or more consecutive steps missing", but there appears to be absolutely NO information available to answer this question with. (except that "some" latters are missing steps, and originally each ladder had "N" steps)

There are the word "different". And you can suppose that there are all possible types of leaders.
