An massless equilateral triangle EFG of side 'a' (As shown in figure) has three particles of mass m situated at its vertices. The moment of inertia of the system about the line EX perpendicular to EG in the plane of EFG is $\displaystyle \frac{\mathrm{N}}{20} \mathrm{ma}^2$ where N is an integer. The value of N is \_\_\_\_.
