Xamarin.Forms SQLite.net data execution

I have SQLite database generated in Sqlite Browser with imported Excel files. It has few tables. Each table has same structure. Columns are: Age, 2000m, 2000f, 2500m, 2500f,... etc.

All i need it to open this database in my Xamarin.Forms Shared project and execute 1 item per time.

Each cell include 1 double number. I need to execute this number and send it to Label on screen.

I don't need to write anything to this database. Only read.

Best way i can imagine is to Execute SQL . like "Select 2000m From Bravo Where Age = 20".

Can someone help me with that?
