In the Namkeen-making industry, 1 kg costs around Rs 100 to 140; you may sell it to whole-sellers for Rs 160 per kg or pack and sell it in the market for Rs 200 per kg. I am sure you will understand. If we talk about monthly earnings, if you start this business with a 5 lakh rupee investment, you may expect to make at least 35 to 40 thousand rupees per month, progressively increasing as your sales improve. Profits will be increased as well.
