How does promotional pricing for monthly rate affect the weekly and daily rates?

Congratulations on finding a bargain for MetroResidences's Singapore serviced apartments! Figuring out how it's calculated? Here's how: all promotional pricing given is reflected in the monthly pricing on the individual corporate serviced apartment listing page. 

The weekly and daily promotional pricing are computed based on the percentage of the monthly promotional pricing. 

Example:

Orginal Pricing of Property (SGD) 
  Monthly    5000 
  Weekly 1400
  Daily 200

If the monthly pricing is reduced to SGD4000, there is a 25.00% discount off on both the weekly and daily rate. As a result, the revised pricing is as shown:

 Discounted Pricing of Property (SGD) 
  Monthly    4000
  Weekly 1050
  Daily 150
