I II III 1 2 3

Consider these to be the 6 places. Consider the 6 heights to be H1, H2, H3, H4, H5 and H6 in increasing order.

It is obvious that H1 has to be at place 1 since H1 is shortest and H6 has to be at place III since H6 is tallest. We only have to worry about H2, H3, H4 and H5. Think about place 2 - People at places 3 and II have to be taller so H4 and H5 cannot come here. Only possibilities - H2/H3 Think about place 3 - Person there has to be taller than person at place 2. Only possibilities - H3/H4/H5 Think about place I - Person there has to be shorter than person at place II. Only possibilities - H2/H3/H4 Think about place II - Person there has to be taller than people at place I and 2. Only possibilities - H4/H5

Now just combine them in all possible ways: H2, H3, H4, H5 H2, H4, H3, H5 H2, H5, H3, H4 H3, H4, H2, H5 H3, H5, H2, H4

firstly I would like to ask..."FUCHS", seriously? the book wrote that? lol

Don't laugh so hard... I know a person from the same country as your avatar hero that uses the same last name in his emails (Fuchs). However, his original last name is with "k" instead of "h". It was funny because every time he would write his last name on the internet some software would ban his posts, so I guess he had to do something about it.

bad question - no logic or formula just painting on the paper. I hope I will not see such questions during real exam.
