@Vishnu Nutakki Thanks for posting your query here!

Firstly, It depends on the number of FD's and UD's you have configured.

Considerings 3 FD'S and 5 UD's - you will have 3 fault domains(3 racks) and 2 of them will have 5 VM's and the other one will have 4 VM's. Please read How do availability sets work? to know how VM's are placed on FD's and UD's

Kindly let us know if the above helps or you need further assistance on this issue.
