Study the following information carefully to answer the questions given below. Seven persons i.e., P, Q, R, S, T, U and V sit in a linear row and all of them face to north direction. Each of them visits different cities for a tour i.e., Jaipur, Udaipur, Agra, Ranchi, Bikaner, Indore and Haridwar. All the information is not necessarily in the same order. One person sits between U and the one who visits Haridwar. U is the only neighbour of the one who visits Jaipur. P sits third to the right of Q. P visits neither Haridwar nor Jaipur. U doesn’t sit adjacent to Q. One person sits between P and the one who visits Ranchi. The number of persons sit to the right of U is same as the number of persons sit to the left of V. More than three persons visit between the one who visits Agra and the one who visits Udaipur. S sits to the right of R and sits adjacent to the one who visits Udaipur. No one sits between T and the one who visits Bikaner.

If all persons are seated in alphabetical order from right to left, how many persons remain in their original positions?
