A, B, C, D, E, F, G sit in row 1 and face north while P, Q, R, S, T, U, V sit in row 2 and face south (but not in the same order as given). Persons of both rows face each other. F is the only neighbor of A. Three persons sit between U and the one who faces F. P sits adjacent to U who does not sit opposite to B. Number of persons sit to the left of P and to the left of D are same. T sits opposite to the one who sits second to the left of C. G sits to the right of C but does not sit at the end.
