I had been pointed to Ramanujan's 1912 article *Note on a set of simultaneous equations* in this answer to my former question about the Solvability of a system of polynomial equations.

While the contents of the paper seemed a bit enigmatic at first reading, I'm now convinced that Ramanujan not only left it to the reader to recover the ideas that had led to the solution but also the motivation to investigate on that special system of polynomial equations.

Questions:

- is anything known about Ramanujan's motivation to work on that problem that somehow doesn't seem to fit his primary research interest; the situation seems analogous to Euler and his characteristic of polyhedra?
- did Ramanujan himself ever refer to the paper in his later work?
- is or was the paper of importance for mathematical research and what are remarkable examples?
- have there been serious attempts to extend the solution method and/or to reduce more general types of systems of polynomial equations to the special case that Ramanujan has solved?
