@ramjn According to this article from June 16, 2015: "When compared with the average demand of 35 per cent for AMT cars in the country, South has registered a demand of 50 per cent or more for Maruti. It means that if Maruti had sold about a lakh units of Celerio (which offers AGS and petrol variants. Diesel has just been launched) across in the country in a year, the average demand for AMT version was 35 per cent pan-India. But in south, AMT-variants accounted for half of the total sales of Celerio in the region."

So, 35%*(20K+5K) per month is about 1 Lakh AMT units per annum.
