When sentences are given, how can we get to know whether the sentence is Akarmak or Sakarmak? Answer Fast please!

I didn't get u!

akarmak kriya the object wil not b given.

eg of akarmak: rahul khata hai

eg of sakarmak : rahul mithai khata hai

eg of akarmak : gaurav rota hai 

eg of sakarmak : gaurav zor se rota hai

akram pustak padhta hai = sakarmak

akram padhta hai = akarmak

hope its clear
