Since this thread is for makuramanche, I hope people won't mind if I put forward one mathematical problem for him.

My dear friend 'nmu' just asked me the following question:

10 motorcycle sales range from $15,000 to $1,500. 25 motorcycles sales range from $16,500 to $2,000. What is the range for total sales of the motorcycle?

I tried but could not come up with any sensible solution. Also, I am not sure how the lowest price increased from $1,500 to $2,000 as the number of motorcycles increased from 10 to 25. Should not it decrease or atleast remain same?
