Im unable to understand

Where did u find issue
It's just simple total no. Of moles i.e. 0.1 mol then 20% of it at n=2 which r already in n=1 so won't change anyhow...50% in n=2 which will give energy getting to n=1 and similarly 30% of 0.1 mol will give energy while going from n=3 to n= 1
Most possibly either u would have made mistake understanding what's exciting state or maybe u won't be knowing the energy at an n ...so that's it...thanks
