A sample multiplication-effect calculation
Addition on 9.12.2012:
The good news for bus fare hike is that the present government and private bus owners have brought down the bus fares. I thank them for their good initiatives. The bus fare is now taken as Rs. 7 instead Rs. 9 (last hiked) or Rs. 6 (old fair). So, literally Rs. 1 increase has taken place. I find the hike as reasonable now and think that the new fair chart will do justice to people's miserable economic conditions.
