Based on the given data, it can be concluded that Muralidhar’s business of manufacturing plastic and paper cups has been successful and profitable. The demand for his products has increased, leading to a significant increase in his turnover. He has also expanded his business by supplying his products to other states.

However, Muralidhar has not registered his business for tax purposes. This may have been advantageous in the past as his turnover was below the threshold for registration. But now that his turnover has exceeded ₹50 lacs, he is required to register his business and become liable for tax payments.

Muralidhar is considering registering only his paper cups venture and continuing his Chai and Coffee shop business without registration. While this may seem like a way to retain the advantage of surplus retention, it is important to note that operating a business without registration can have legal and financial implications. It is advisable for Muralidhar to consult with a tax professional or accountant to understand the tax obligations and benefits of registration for both his businesses.

Overall, the data suggests that Muralidhar’s businesses have been successful and have the potential for further growth. However, it is important for him to comply with the necessary legal and tax requirements to ensure the long-term sustainability and success of his ventures.
