Interesting to learn about this argot of boatmen of Prayag, which they use to communicate among themselves for the purpose of excluding their clients.
1 = sang संग; 2 = jōṛ जोड़, 3 = rakh रख; 5 = hāthū हाथू; 10 = salāī सलाई; 50 = tālī ताली; sunna सुन्न = 100 and so on. In this way rupees 500 = hāthū sunn हाथू सुन्न. And this would be conveyed to the next boatmen in no time.
