Study the following information carefully and answer the given questions: Nine persons A, B, C, D, E, F, G, I and J sit around a circular-shaped table, and all of them face towards the centre, but not necessarily in the same order. G sits third to the right of C. One person sits between C and I. E sits third to the left of I. One person sits between E and D. J sits third to the right of B. J and G are not immediate neighbours of each other. B is not an immediate neighbour of E. The number of persons sit between I and A when counting from the right of I is one less than the number of persons sit between E and F when counting from right of E.
Question: How many persons sit between F and D when counted clockwise from F?
