They should increase fares of slipper by 10-15%. But clearly they are reducing the number of berths in general quota and increased the number of berths in tatkal and premium tatkal quota. Now not to worry about the losses to trains because of sleeper coaches. They are charging express fare to passenger trains in the name of special trains. And anyhow, the losses will be almost covered from the income from the freight which will be indirectly born by the people. Also, there is a huge increase in passenger revenue compared to previous year due to hiked charges.
