Takes 6 boydays to download a song
(BD)/6=S (6*6)/6=S 6=S (12*12)/6=S 24=S
takes 4 girldays to download a song
(GD)/4=S (4*4)/4=S 4=S (12*12)/4=S 36=S

24 songs downloaded by boys

...or because there are three of each, and one of those is blue and two are red...

or because it goes diagonally 5,3,2,5 so 3 comes next

. I can always think up other patterns - used to make all the tests difficult , I had to try and work out which one would be considered correct

Hmm, I've narrowed it down to 3 or 4, but which is it? My guess is 4.
