A hydrogen like atom (atomic number Z) is in a higher excited state of quantum number n. This excited atom can make a transition to the first excited state by successively emitting two photons of energies `10.20` and `17.00 eV` respectively. Alternatively, the atom from the same axcited state can make a transition to the second excited state by successively emitting two photons of energy `4.25 eV` and `5.95 eV` respectively. Determine the values of n and Z `("ionisation energy of hydrogen atom"=13.6 eV)`. Given answer `=n+Z`.
