We have opened a plywood and hardware shop. We have obtained GST number also.

Suppose we are buying goods at Rs 100 and 18% on that. We received at 118. Now we have 10% profit.

please tell me on which price we should add profit and then Gst thereon. At 100 Rs or at 118?
If we add at 100 then selling price would be 110 plus gst or at 118 then 129 plus GST. Will we get ITC?

which is correct???
