Marks obtained by the seven students of a tuition class, P, Q, R, S, T, U and V, are mentioned. P scored second highest marks in the class. Marks scored by V were more than only one of the persons. S's score was more than T but less than P. Three people got higher than T and three got lesser than T. Neither R nor Q received the lowest marks. Given that no two students have the same marks, whose marks were the lowest?
