Based on the suggested duplicate, let me reformulate my question:
If chmod 0660 path/to/folder is run, and user A isn't in the relevant group, could user A still read /path/to/folder/file.txt if that file has the appropriate octal?
filesystems chmod gnu

Renu, oh dear, I picked the wrong question on the duplicate... I meant this one: Execute vs Read bit. How do directory permissions in Linux work That's the one I was reading all along. My bad.

If /path/to/dir has the permission bits 0660, then no-one can access /path/to/dir/file.txt, since no-one has the x permission on the directory dir. (In general, they can't even see the type, size or permission bits of file.txt, but some filesystems may reveal some of that data.) The owning user and members of the owning group can list the directory contents (the files within), since they have the r permission. The w permission isn't really useful without the permission.
