why fees difference in institutes of allen even of same class is only because of Different city ya some other reasons also???
See the fees difference can be due to multiple reasons. But in general the fees difference are caused to the Market Price Index. For cities we have a certain index depending upon which the market price is decided. So a teacher residing in a city will have to spent more money for buying commodities. So the fees to be paid to those teachers will need to paid higher than that of Allen Institutions in any Semi Urban area.
I hope you get my point. This can be one of the reason for fees difference. Although this is not a official information provided by Allen but just a personal reasoning.
I hope my answer helps. All the very best for your future endeavors!
