Directions: Study the following information carefully and answer the questions given below:
Eight workers I, J, K, L, M, N, P and Q are sitting around a circular table but not necessarily in the same order. Some of them are facing outward. They are working at four stalls, viz Cloth, Food, Footwear and Books, in a trade fair. Two persons are working at each stall.
Note: Facing the same means if one face the centre then the other person also faces the centre and if one person faces outward then the other person also faces outward.
Facing opposite directions means if one person faces the centre then the other person faces outward and vice versa.
How many persons are facing outward?
