Given your space constraints, I think it would be best to hang the TV on the wall that is common to the study/living room (just to the right of the door entry). You could get two or three small upholstered chairs for the living area (gives you flexibility in moving them around.) I would have a table surface hung so it can swing out and be used on the wall between the door and the opening to the kitchen. If hung with a hinge attachment so it can be flat on the wall when not in use, you still have space to move around. Backless bar stools could be lined up on that wall when the table is stored flat to the wall, and still be used for more guest seating.

ok pls provide me more details

This is possible. Black pen shows the placement of dining table, red line shows the partition at the entrance to avoid the direct vision of dining area from the entrance, red cross shows the kitchen entry which will be shifted from the present entry.

provide your views please
