Circular Arrangement Facing Centre

Seating Arrangement: Arrangement is the positioning of things, persons, etc. in a particular order.Seating arrangement is the manner in which people are arranged to sit around a table, in a row etc.

Circular Arrangement - Facing Centre: In a circular arrangement, persons are arranged around a circular table, according to certain conditions.Here we are discussing the arrangement in which all the people are sitting around a circular table facing towards the centre of the table, or certain objects placed in a circular order with their faces towards the centre. In circular arrangement  Right means Anti - clockwise Direction and Left means Clockwise Direction

Rules for Solving Circular Arrangement Problems:

  • Firstly, mark the number of points which is equal to the number of persons or objects.
  • The points on the circle should be equidistant from each other
  • Fix the position of one person according to the given directions and arrange the positions of the rest.
  • If it is written that a person is sitting to the right or left of a certain person, it does not mean that the person is sitting to the immediate right or to the immediate left.
  • If eight persons are to be arranged who are facing the centre, then make eight marks on the circle which are equidistant from each other.
  • Illustration: P, Q, R, S and T are sitting around a circular table facing the centre. R is to the immediate right of P and is second to the left of S. T is the immediate neighbour of both R and S. Who is sitting around to the left of R?

    A. R                   B. S                  C. T                 D. Q

    Answer: D

    Solution : Q is sitting second to the left of R.

  • Draw a circle and mark as many cuts as the number of persons to be arranged . Here, it is 5.
  • FIx the position of one of the persons at any place and arrange the rest of the persons accordingly.
  • Clearly, R is to the right of P and is second to the left of S. 
  • Since T is not between P and S, so Q comes between P and S or Q is second to the left of R.
  • Thus, answer is Q.
  • Illustration: Study the following information carefully to answer the given questions :

    A, B, C, D, E and F are seated in a circle facing centre. A is second right of D who is third left of F. C is third right of E and is not immediate neighbour of F.

    Question: - What is position of B with respect to C ?

    A. Second to the left                 B. Third to the right                   C. Second to the right                D. Third to the left

    Answer : - A   B is second to the left of C.

    Solution: In facing centre, left means clockwise direction and right means anticlockwise direction so according is this, the valid diagram is:

  • A is second right of D, we will first mark any position as A then we will mark D to the second left position, we are marking the left of A so the condition that A is right to D is satisfied.
  • Now D is third left of F. we will mark F to the third right  position to D, We are marking in right direction because we are marking with respect to F and in the statement we are given the position of F with respect to D. So it will be immediately right to A
  • C is not immediate neighbour of F. also C is third right of E  so only position where C can marked is between A and D and E will be marked at the immediate right position to F, because only then the condition that C is third right to E will be satisfied.
  • The vacant Position is marked as B
  • From the diagram it is clear that B is second to the left of C. So option A Second to the left is correct.
