What the question simply means is that Nac's hotel has a total of 128 rooms,out of which, 25% of the rooms(which is 32 rooms) doesn't have sea view. Hope that's what you asked for.. :)

Answer 2

Nac's hotel has 128 rooms ok
first. let the half % of total rooms = 128÷2=64.
second. let the half of 64 = half of 50% = 25%
third. let the half of 64 = 64÷2 = 32 
so, 32 rooms of hotel did not have an ocean view.
