Explanation:

E = energy absorbed = 12.75 eV

n₂ =principle quantum number value in excited state = ?

energy absorbed in case of hydrogen is given as  

Energy in excited stated = energy in ground state + energy absorbed  

Energy in excited stated = - 13.6 + 12.75  

Energy in excited stated = - 0.85 eV

- 13.6/n^2₂ = - 0.85

n₂ = 4
