Answer-How many persons sit in the row?

V sits fifth from one of the extreme ends of row and sit second to the right of U. It is clear that V sits fifth from the right end and U sits seventh form the right end. Q sits fifth to the left of U. So, Q sits twelfth from the right end. T sits third to the left of V. So, Q sits eighth from the right end. Three persons sit between R and U. So, R sits eleventh form the right end of the row. R sits fourth to the right of P. So, P sits fifteenth from the left end. Four persons sit between S and P. P sits second from one of the extreme ends of row. So, S will sit seventh from the left end.
