Translation:At what time will Raj sleep?
OR - what time will raj go to sleep? - more likely english use??
How about the English translation For how many hours will Raj sleep?
Is it right?
that would be — राज कितने घंटे सोएगा or राज कितने घंटों के लिए सोएगा
I think you'll need ke lie and then the oblique form
When will raj sleep?
