I just want to buy a Pangu guy which is 122 but and in such a low price which is like a one or two lakhs

Do you mean a Punganur cow for dairy? If yes, at one to two lakh rupees, first check milk yield, calving history, age, and udder health. For a small dairy cow, Punganur is usually kept for low feed cost and good fat milk, but exact price depends on age, pregnancy, and location. If you want, I can help you shortlist the right cow to buy.
