Depending on the features and use of the UPS, the fairly cheap device can range from Rs.2000 - Rs.6000. Though more expensive UPS' are also out in the market, they either provide a higher grade of power supply potential or extra features such as a higher count of sockets, a digital display and replaceable batteries. A bigger and better ability to supply power would directly result in the UPS staying on and supplying power to devices for a longer duration. Cost alone though will not decide the best UPS for PC in India.
