APWJ exercises for the reader [3 of 4]

[Ian Clark-6]

In At Play With J Edn 1, there were 4 questions left as exercises for
the reader. In Edn 2 we want to provide the answers in an Appendix.

Just so I don't get them wrong, could the forum please suggest what
the answers should be? You may have to refer to the Wiki page.

I'm putting each question in a separate thread.

"Here are the rest of the questions Amy had to answer. See if you can
answer them.
   A. What do you notice about the lockers that were touched by
exactly two students? (Try m19 >: 2=dc )
   B. What do you notice about the lockers that were touched by
exactly three students?
   C. What do you notice about the lockers that were touched by
exactly four students?
   D. What was the first locker touched by both student 6 and student 8?
   E. What do you notice about the student numbers of the students
that touched both locker 24 and locker 36?
   F. Which students touched both locker 100 and 120? What do you
notice about their student numbers?"
