Draw a Venn diagram with three loops inside a box. Make sure that all the loops overlap including a triple overlap. Label the loops F, G, R.

Now fill in the sections that you know starting with the inside. 26 are in the triple overlap. Now 55 take F and G but not R so since 26 are already in the triple overlap you need an extra 29 in the part that is inside the F and G loops but not in the triple overlap.

Continue like that. My suggested order is, 57 G and R, 18 F only, F and R, G only, R only, none.
