It all depends on you age and gender.
Generally, a younger male applicant is expected to do a lot more pushups than an older female applicant.
Same idea goes for the situps, and the running.
Just make sure you can do at least 25 pushups, and 25 situps before basic training. It'll be easier if you prepare yourself that way.
And always remember, "failing to prepare is preparing to fail"
