Kahan kho gaye hain?
Not sure if it's right written, it means "where have you disappeared" but is it the formal/plural form? what would be the friendly form? Or the formal ? Or all of the possible forms? Here it doesn't say aap or tum... so I'm confused :(

Aap kaisi ho ? How are U ?

In this sentence ' AAP '  (you) is assumed (hidden)  since the use of GAYE (form of verb). If U R to make Past tense sentence :  TUM  KAHAAN  KHO GAYAA  or  THA.  However, invariably U use  AAP form to give respect.
