How many persons sit between P and R?

P sits fifth to the right of U. Here we have two cases which is Case-1 and Case-2. Q sits fifth to the left of V. Only one person sits between S and T. Neither U nor Q sits near to S. Here we have only one place left for R. The one who order from Myntra sits second to the right of R. There are three persons sit between the one who order from Myntra and the one who order from Wallmart. The one who order from Flipkart sits third to the left of P. The one who order from Paytm sits immediate right of the one who order from Myntra. The one who order from Meesho sits immediate left of the one who order from Snapdeal. Hence Case-2 is eliminated.
