The given table shows the production of foodgrains A, B and C and their export (as a percentage of production) over five years from 2015 to 2019, Study the table and answer the questions that follow.
Production = Domestic Consumption + Export
In 2020, the production of foodgrain A increased over 2019 by the same percentage as in 2019 over 2018, and the production of foodgrain C in 2020 increased by 35% over 2019. If the export of both foodgrains was 40% of their respective production in 2020, then what was the total domestic consumption (in million tonnes) of these two foodgrains in that year?
