DAX average of two attributes from two tables

[Sohan]

I have three measures. 

1. Calculated the number of appointments a practitioner has.
   
   CALCULATE(COUNT(Afspraken[Patiëntnummer]),

   FILTER(Afspraken, Afspraken[Soort afspraak]<>"Phone call"),

   FILTER(Afspraken, Afspraken[Status]="Done"))
   
   
2. Calculated the revenue generated by said practitioner.
   
   CALCULATE(SUM(Verkoopboekingen[Bedrag (excl. belastingen)]),

   FILTER(Verkoopboekingen, Verkoopboekingen[Grootboekrekening]<>8505))
   
   
3. The division of the two above.
   
   DIVIDE('Gemiddelde behandelomzet per dag'[Omzet per dag], 'Gemiddelde behandelomzet per dag'[Aantal afspraken])
   

   However number three does not give the correct value back. Does anyone know why?

@Sohan , Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.

Try the first one like this and check

CALCULATE(COUNT(Afspraken[Patiëntnummer]),
FILTER(Afspraken, Afspraken[Soort afspraak]<>"Phone call" && Afspraken[Status]="Done"))
