In a container a mixture is prepared by mixing of three samples of hydrogen, helium ion $\left({\mathrm{He}}^{+}\right)$ and lithium ion $\left({\mathrm{Li}}^{2+}\right)$. In sample, all the hydrogen atoms are in 1st excited state and all the He+ ions are in third excited state and all the ${\mathrm{Li}}^{2+}$ ions are in fifth excited state. Find the total number of spectral lines observed in the emission spectrum of such a sample, when the electrons return back to the ground state.
