 Directions (1-5):  Answer the following questions based on the given statements.

Certain number of persons are sitting around a circular table, which has a circumference of 570 cm. All the persons are facing towards the center. They are sitting at distance to each other which are consecutive multiple of five. Only three people sits between A and T. The distance between A and R is 45 cm. The distance between A and P is more than 55 cm. The distance between R and P is 150 cm. The distance between P and W is 105 cm. W is not the immediate neighbor of R. W sits on the immediate left of X. Only three persons sit between X and U. U is not the immediate neighbor of A and R. The distance between S and C is 55 cm. S sits 4^th to the right of B. The distance between Y and P is LCM of 25 and 2. D sits third to the right of Y.

Explanation:

1) Certain number of persons are sitting around a circular table, which has a circumference of 570 cm. So, the distance between persons is 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70 and 75. From that condition we can deduce that there are only 12 persons in the circle.
