Of these, fifteen would contain good quality ghee and the remaining could be adulterated. He would mix the two and sell it. This went on for a long time, till finally the people fed up of being cheated, complained to Haripant.
Haripant had the ghee examined and found to it be adulterated. He gave Niranjan a choice of punishment-drink the five barrels of adulterated ghee from his shop, or receive a hundred lashings, or pay a thousand gold coins to the treasury.

After ten lashes, he started trembling and by twenty he was giddy. ‘Stop!’ he screamed. ‘I will pay the thousand gold coins!’ And he handed them over.
