Bengaluru, Oct. 11 -- Amid growing criticism over the recent Metro fare hike, Bengaluru South MP Tejasvi Surya has raised serious concerns about the methodology used by the Bangalore Metro Rail Corporation Limited (BMRCL), claiming it was riddled with serious "mathematical errors".

In a strongly worded letter addressed to the BMRCL, Surya accused the agency of using faulty calculations to justify a steep fare revision, said a report by The New Indian Express. Even high school students could do better math, he said, pointing out that BMRCL wrongly calculated a 105 per cent hike, when the actual increase, based on the correct formula provided by the Fare Fixation Committee (FFC), should have been closer to 50 to 55 per cent.
