when running out of time or if we get stuck, we can eliminate few options by analyzing them...
option A does not have s at all...s is needed to determine the new rent
option D does not have k, we need k as total occupancy needs to be considered.

we dont need p (old revenue) to determine new revenue as long as we have new rent and occupancy info.
we can eliminate B and C

A Commonwealth condominium complex has \(k\) apartments, \(n\) of which are rented at \(s\) dollars a month, providing a total monthly revenue of \(p\) dollars. If the management is planning to decrease the rent by \(m\)%, to increase the occupancy to 100%, how much total revenue will it collect?

A. \((k-n)\frac{p}{m}\)
B. \(k*\frac{s}{p}*\frac{m}{100}\)
C. \(k+\frac{s}{p} + km\)
D. \(\frac{sp}{100m}\)
E. \(ks(1 - \frac{m}{100})\) --> correct
Solution:
`-----------------------------------------------------------| before| after |
rent=>|decrease the rent per apartment by m % | s------| s*(1-m/100)|
number of apartments rented =>--------------------|n------|k = 100% |
Total revenue =>---------------------------------------|p=ns--|=ks(1-m/100)|

This is straight forward question which needs more clarity in question stem. As a reader, there is confusion if the rent for the rest of the apartments were increased or for all the K apartments. Not sure if it is just me, but I spent 7 minutes because of this confusion on solving.

The question clearly states that the management plans to reduce the rent to achieve 100% occupancy, meaning the new rent applies to all k apartments. There is no mention of different rents for different groups of apartments. The confusion comes from overinterpreting the problem—reading it carefully makes it clear that the reduced rent applies to all units.
