The material conditions of people within India are just as important when putting things like this in context. The minimum wage for unskilled workers in New Dehli is equivalent to a salary of $202.64, or $0.10/hr. That pizza is insanely expensive for people in India.
Legal minimum wage in Delhi 663 rs per day. Which is about $.80/hr. https://labour.delhi.gov.in/sites/default/files/Labour/generic_multiple_files/minimum_wages_current.pdf
I don’t know where you’re getting the numbers on that conversion, 663 rs is equivalent to $8.08.
From your same source, I rounded up to 16800 rs and divided by 2080 (40/hr weeks for 52 weeks), which came out to 8.08 rs/hr, which converts to $0.10/hr. it doesn’t seem to me that the daily wage is equivalent to the yearly wage. With a complete shot in the dark, it seems like that’s intentional as a poor attempt to dissuade the use of short term labor.
That 16800 rs in the source is per month not per year. If it is 663 rs ($8.08) per day and lets say 10 hours of work per day then it is $8.08/10 ~= $0.80 per hour.
