" कीजे/kije " was often used in old hindi and Urdu poems . It has now been replaced by " कीजिये/kijiye " in the modern Hindi. Its meaning and use is similar to " karen/करें " and it means " to do " , the only difference is that " karen/करें " is used in informal situations while " कीजिये/kijiye " is used in formal situations. " kya kijiye " ( kya kije ) :- what to do? mujhe " maaf kijiye/ माफ़ कीजिये ":- " forgive/pardon " me . कुछ कीजिये( kuch kijiye ) :- Do something. " अफ़सोस मत कीजिये /afsos mat kijiye " - " don't regret/feel sorry " ( here, afsos means to regret )

its kya kijiye(कीजिये) it mens do/doing something. i dont know which song your are taking about here lets take this one(famous hindi song) dil to hai dil dil ka aitbaar kya kijiye दिल तो है दिल ,दिल का ऐतबार क्या कीजिये: it means heart is herat after all ,how to trust it(how one can do trust on it) dil= heart to=so/and (here the meaning is after all ) hai=is aitbaar=trust kya=what/here the meaning is how kijiye= do another example is - solve this math question/iss ganit prashan ko hal kijiye(इस गणित प्रशन को हल कीजिये) iss=this ganit=math prashan= question hal= solve kijiye= do (do solve this)

tushar haven't you ever seen this (kijiye) in hindi questions in school?

'kije' is not generally what we use in day to day conversation. 'kije' is form of the verb karna - to do. so it should be, according to context and my understanding 'kya kije' - 'what to do?'. Let it be confirmed by someone, who uses it. Because i have listened it in songs and poetry only, so i cannot give a authentic guide to this verb form.
