After a while both agreed that the book was definitely better.
Assuming that the quality ratio is 9 (according to my taste) list all possible solutions (19, I believe) of the following alphametic:
STORY/FILM=9 ....... (i)
Rem: 3 solutions out of 19 are zero-free !
d4 Bonus:
Instead of the number 9 select another integer N and define #(N) as the number of distinct solutions of the alphametic (i) with a ratio n.
Solve the alphametic.
List the values of #(N) for N=2,3,4,....8.
