Tech Start-up valuation method - question

Hi everybody. 

I am trying to solve a business case and I came across what seems to be a very odd valuation method that I need to use. I simply can't understand how I can use it in a logical way. Can any of you make sense of it? Thanks a lot.

There are 3 major factors that influence the valuation with different weights as described below:

• 50% of the valuation multiple is dependent on revenues
• 25% is dependent on the company growth. 
• 25% is dependent on the market factors. 

To offer a bit more background, the company is offering a SaaS B2B solution, had revenues of 100K for the year, has a current valuation of 2M and received seed funding of 400K. The target would be to increase the valuation for the next 6 months by 50% and my task would be to show how it could be done. The issue I am having is with the method of valuation. 

Any help would be much appreciated.

Thank you
