How much to pay under composition scheme

As per you're query, let me tell you if in case you're supplying a food products in packets and all to the customers then the situation will be considered as manufacturing. In this case the GST applicable will be 2%

But in cases where you're supplying a mere snack (bhujia) to the customers in a restaurant or something then the GST applicable will be 5%
